Meaning of Life Essay Example for Free

Meaning of Life Essay Heres what a recent survey found: †¢ 25% of people say it is to seek truth and create meaning for yourself †¢ 22% think the meaning of life is to lovingly help others and make the world better †¢ 18% say there is no meaning †¢ 8% think it is to reproduce and continue your genes and the human race †¢ 8% say it is to find happiness †¢ 6% believe it is to learn how to serve and worship God, while †¢ 8% don’t know While it seems there are several purposes to life, science is beginning to reveal there is one fundamental purpose to all life. Every moment of your existence your body works to keep energy flowing. Every second you breathe air, you add food and water to replace the energy you use. Everything you sense or do is connected to the flow of energy in one form or another. You are so used to this energy flow that you hardly notice it. It is the ultimate process of your life. If your energy stops flowing you die: flowing energy differentiates living creatures from dead ones. While the purpose of all life might be to help energy flow, the same laws of energy indicate that a meaning of your own life is to find how your energy flows best. Is this science echoing those scriptures that suggest you have your own unique ‘gift’ that you should use? What does your energy enable you to do best? This can be as simple as determining what you are truly passionate about or what you do better than anyone else. Unfortunately, many of us are not aware of what this is. As such, the individual meaning of your life is for you to discover what makes your energy flow best and then how to do that. How you use energy best varies for everyone therefore, everyone has a slightly different meaning to someone else. Ignoring this means your energy will be all mixed up and your life will be chaotic. This is what most scriptures and spiritual writings are trying to tell us, but just didnt understand energy well enough. If you look at ancient scriptures and spiritual writings in terms of energy you start to realise that they, and modern science, are all saying something similar. In short, while the purpose of all life is about helping energy flow, spread and balance, your individual meaning is about determining how you do this best, what you do that helps your energies flow best.

Gothic vs. Romanesque Architecture Essay -- Architectural Style Buildi

Gothic vs. Romanesque Architecture Missing Figures Where are you when you wake up? Where are you when you are learning? Where are you when you go to pray? Where are you when you go to work? Where are you when you are having fun? The answer is that you are in a building or structure of some kind and style. All of the buildings and structures that one sees around them is designed and built with much thought and care. They are all designed and built by what we call architecture. According to Merriam-Webster’s Collegiate Dictionary architecture is â€Å"the art or science of building; specifically: the art or practice of designing and building structures and especially habitable ones, a method or style of building†. Architecture is a science according to Merriam-Webster because it is â€Å"a department of systematized knowledge as an object of study, something that may be studied or learned like systematized knowledge† . This can be seen as that buildings and structures have certain rule and laws that apply to them when they are design, constructed and inhabited. Architecture is an art according to Merriam-Webster because it is â€Å"the conscious use of skill and creative imagination especially in the production of aesthetic objects† . This can be seen as that buildings and structures do not only follow form and function but expression and feeling. Architecture has basically three steps. They are design, construction, and usage of the space or how the space is inhabited. Architecture is to building or structure as literature is to a book or novel.  Ã‚     Ã‚  Ã‚   Over the course of western history there has been many periods and styles of architecture, spanning from pre-history where mainly stone and timber were used to the 20th century where glass and steel seem to have seemed to take over. Each style and period have given there own part to today’s architecture such as the Greek’s ideas of columns, to the Roman’s usage of arches, to the Industrial Age of building with iron, steel and glass. When buildings and structures were first constructed there was very little interior space and there was much more emphasis on exterior space, such an example is that of the Greek and Roman architecture. The reason that there was more emphasis on one then another was simply because of the technology and techniques that was available at the time and the limited amount of ideas and unders... ...these styles have there own elements and also share some elements. Today both of these styles can both be seen in use today. The round arch and barrel vault are still used and stained glass and flying buttresses are still used today. To be able to look around the world today and see the buildings and structures that were built during the Romanesque and Gothic period of architecture is amazing. During those periods the advancements that were made would allow their buildings and structures to last hundreds of years. To be able to go to Europe and see the same buildings and structure that were seen over hundreds of years ago is unbelievable. Even though there have been great advancements in architecture over the years the basic of much of today’s architecture goes back to the Romanesque and Gothic period and other periods of architecture. It was from the great ideas of these periods that the great ideas of the present come. The courage and ingenuity of the people of the past helps the people of today challenge what they can do and pushes them to strive further. So with what was done before makes what is done today possible and helps to push the ideas and concepts into the future.

For left-handed people who live in a world designed for right-handed people, the same may  not  be true. To test this, muscle strength was measured on the right and left hands of a random sample of 15 left-handed men and the difference (left – right) was found. The alternative hypothesis is one-sided (left hand stronger).The resulting t-statistic was 1. 90. This is an example of A)  a two-sample t-test. B)  a paired t-test. C)  a pooled t-test. D)  an unpooled t-test. Feedback:  Since two measurements were taken per individ ual (i. e. for each man sampled muscle strength was measured on his right hand then his left hand) this would be a study using paired data. Points Earned:| 1. 0/1. 0| | Correct Answer(s):| B| 19. It is known that for right-handed people, the dominant (right) hand tends to be stronger. For left-handed people who live in a world designed for right-handed people, the same may  not  be true.To test this, muscle strength was measured on the right and left hands of a random sample of 15 left-handed men and the difference (left – right) was found. The alternative hypothesis is one-sided (left hand stronger). The resulting t-statistic was 1. 90. Assuming the conditions are met, based on the t-statistic of 1. 90 the appropriate decision for this test using ? = 0. 05 and using  T-Table  is: A)  df = 14, so p-value < 0. 05 and the null hypothesis can be rejected. B)  df = 14, so p-value > 0. 05 and the null hypothesis cannot be rejected. C)  df = 28, so p-value < 0. 05 and the null hypothesis can be rejected.D)  df = 28, so p-value > 0. 05 and the null hypothesis cannot be rejected. Feedback:  From  T-Table  and degrees of freedom equal to 15 ? 1 = 14 and a t-statistic of 1. 90, the p-value is between 0. 025 and 0. 050 which is less than 0. 05 making the appropriate decision to reject Ho. Points Earned:| 1. 0/1. 0| | Correct Answer(s):| A| 20. A shoe company wants to compare two materials, A and B, for use on the soles of boys' shoes. In this example, each of ten boys in a study wore a special pair of shoes with the sole of one shoe made from Material A and the sole on the other shoe made from Material B.The sole types were randomly assigned to account for systematic differences in wear between the left and right foot. After three months, the shoes are measured for wear. Let Ho: ? d  = 0 versus Ha: ? d  ? 0. From this random sample of 10 boys, the sample mean difference was 0. 41 and Sd  was 0. 387. If the p-value for this t est is 0. 009, then for a significance level of alpha = 0. 05, are the results statistically significant? A)  No, results are not statistically significant because the p-value < 0. 05. B)  Yes, results are statistically significant because the p-value < 0. 05.C)  No, results are not statistically significant because the p-value > 0. 05   D)  Yes, results are statistically significant because the p-value > 0. 05. Feedback:  Yes, results are statistically significant because the p-value < 0. 05. Points Earned:| 1. 0/1. 0| | Correct Answer(s):| B| 21. The maximum distance at which a highway sign can be read is determined for a sample of young people and a sample of older people. The mean distance is computed for each age group. What is the most appropriate  null  hypothesis about the means of the two groups? A)  The population means are different.B)  The sample means are different. C)  The population means are the same. D)  The sample means are th e same. Feedback:  The null hypothesis, Ho, would indicate that there is no difference and that this would take place in the population. The sample is used to test for a population difference. Points Earned:| 1. 0/1. 0| | Correct Answer(s):| C| 22. The p-value for a one-sided test for a mean was 0. 04. The p-value for the corresponding two-sided test would be: A)  0. 02 B)  0. 04 C)  0. 06 D)  0. 08 Feedback:  When we go from a 1-sided test of hypotheses to a 2-sided test we would double the p-value.Conversely, going from a 2-sided to a 1-sided we would cut the p-value in half. Points Earned:| 1. 0/1. 0| | Correct Answer(s):| D| 23. A shopper wanted to test whether there was a difference in the average waiting times at the check-out counter among 5 different supermarkets. She selected a random sample of 20 shoppers from each of the five supermarkets. What is the alternative hypothesis for this situation? A)  The average waiting time to check out is 25 minutes for all f ive supermarkets. B)  The average waiting time to check out is the same for all five supermarkets.C)  The average waiting time for each of the 100 shoppers is different. D)  The average waiting time to check out is not the same for all five supermarkets. Feedback:  The alternative hypothesis for an ANOVA test is that all the means are not the same, i. e. the means are not all equal. Points Earned:| 1. 0/1. 0| | Correct Answer(s):| D| 24. Which one of the following choices describes a problem for which an analysis of variance would be appropriate? A)  Comparing the proportion of successes for three different treatments of anxiety. Each treatment is tried on 100 patients.B)  Analyzing the relationship between high school GPA and college GPA. C)  Comparing the mean birth weights of newborn babies for three different racial groups. D)  Analyzing the relationship between gender and opinion about capital punishment (favor or oppose). Feedback:  The dependent (response) v ariable needs to be continuous and the different levels of the independent variable need to be mutually exclusive and categorical. This leads to the correct answer of mean birth weights (continuous response) across three racial groups (mutually exclusive, categorical). Points Earned:| 0. /1. 0| | Correct Answer(s):| C| 25. A study compared grade point averages (GPA) for students in a class: students were divided by 6 locations where they usually sat during lecture (i. e. left or right front, left or right center, left or right rear). A total sample size of 12 students was studied (2 students from each section) using one-way analysis of variance. What are the numerator and denominator degrees of freedom for the ANOVA F-test? A)  6 for numerator and 12 for denominator. B)  5 for numerator and 11 for denominator. C)  5 for numerator and 6 for denominator.Feedback:  The numerator degrees of freedom are found by taking the number of group levels minus 1 (this case 6 ? 1 = 5) and the denominator degrees of freedom are found by taking the total sample size minus the number of group levels (12 ? 6 = 6) Points Earned:| 0. 0/1. 0| | Correct Answer(s):| C| 26. A study compared testosterone levels among athletes in four sports: soccer, track, Lacrosse, and water polo. The total sample size was n =30 (10 soccer, 10 track, 5 Lacrosse, and 5 water polo). A one-way analysis of variance was used to compare the population mean levels for the four sports.The sum of squared errors is SS Error = 100. What is the value of the Mean Square Error (MS Error)? A)  10 B)  3. 45 C)  3. 85 Feedback:  The MS Error is equal to the SS Error divided by the Error degrees of freedom (which are equal to the total sample size minus the number of group levels: 30 ? 4 = 26). Therefore, the answer is 100/26 = 3. 85 Points Earned:| 1. 0/1. 0| | Correct Answer(s):| C| 27. On a survey conducted at a university, students were asked how they felt about their weight (about right, overweight , or underweight), and also were asked to record their grade point average (GPA).There were 235 responses, with 160 saying their weight was about right, 50 said they were overweight, and 17 underweight. The question of interest is whether mean GPA is the same or differs for different weight attitude populations. The test F-statistic value is 4. 98. The p-value of 0. 008 is found by calculating: A)  the area to the right of 4. 98 under an F-distribution with 2 and 232 degrees of freedom. B)  the area to the right of 4. 98 under an F-distribution with 2 and 234 degrees of freedom. C)  the area to the right of 4. 98 under an F-distribution with 2 and 231 degrees of freedom.Feedback:  The p-value is the probability of being greater than the F-statistic or simply the area to the right of the F-statistic with the corresponding degrees of freedom for the group (number of group levels minus 1, or 3 ? 1 = 2) and error (total sample size minus the number of group levels, or 235 ? 3 = 232) Points Earned:| 1. 0/1. 0| | Correct Answer(s):| A| 28. Ninety people with high cholesterol are randomly divided into three groups of thirty, and a different treatment program for decreasing cholesterol is assigned to each group.The response variable is the change in cholesterol level after two months of treatment. An analysis of variance will be used to compare the three treatments. What null hypothesis is tested by this ANOVA F-test? A)  The sample variances are equal for the three treatment groups. B)  The population variances are equal for the three treatments. C)  The sample means are equal for the three treatment groups. D)  The population means are equal for the three treatments Feedback:  The null hypothesis for an ANOVA test is that all population means are equal. Points Earned:| 0. 0/1. 0| | Correct Answer(s):| D| 29.A study done by the Center for Academic Integrity at Rutgers University surveyed 2116 students at 21 colleges and universities. Some of the sch ools had an â€Å"honor code† and others did not. Of the students at schools with an honor code, 7% reported having plagiarized a paper via the Internet, while at schools with no honor code, 13% did so. (Sacramento Bee, Feb 29, 2000, D1. ) For this study, which of the following statements about percent increase in risk is correct? A)  There is a 185. 7% increase in the risk of plagiarism at a school with no honor code, compared to a school with an honor code. B)  There is an 85. % increase in the risk of plagiarism at a school with no honor code, compared to a school with an honor code. C)  There is a 53. 8% increase in the risk of plagiarism at a school with no honor code, compared to a school with an honor code. D)  There is a 6% increase in the risk of plagiarism at a school with no honor code, compared to a school with an honor code. Feedback:  The percentage increase is found by taking the difference in risks between one group minus the baseline and then dividi ng this difference by the baseline risk. Here the answer that makes sense is one using the â€Å"with honor† as the baseline.Doing so produces: (13%-7%)/7% = 85. 7% increase in plagiarism from â€Å"with honor† to â€Å"without honor†. Points Earned:| 1. 0/1. 0| | Correct Answer(s):| B| 30. Which of the following variables  COULD  be used in a Chi-Square analysis?
