Questions are in attached file. The free program Jamovi was recommended by our professor.
These are the problems for the first problem set that are due Friday October 18th by 5 pm Central Time. Please answer the questions by using full English sentence to explain the answers. Give a short summary of each problem first and have some text for each section of the answer. In most problems simply putting down a number is not enough. I want to see in the test you understand what the number you have calculated means, or what the concepts given mean in terms of the problem. I want to be convinced you know what the answer means as well as getting the correct answer. Cite the sources used both in the text of answer and at the end of the paper in a references cited section. This includes any software used and the main textbook. Please look at the examples I have posted of what I think are good answers to questions. If a problem requires a hypothesis pair to be written be sure to include those explicitly as part of your answer. 3.23, 4.23 (5 points), 5.26 (5 points), 6.16 (5 points), 6.21 (5 points), 8.21, 8.25, 9.27, 10.17 (5 points), 10.19, 11.22, 12.33, 13.25 (5 points) 3.23 A eunuch is a castrated human male. Eunuchs were often used as servants and guards in harems in Asia and the Middle East. In males of some mammal species, castration increases life span. Do male eunuchs also have long lives compared to other men? The accompanying graph shows data on life spans of 81 male eunuchs from the Korean Chosun Dynasty between about 1400 and 1900, according to historical records. These data are compared with lifespans of non-eunuch males who lived at the same time, and who belonged to families of similar social status (n = 1126, 1414, and 49 for the three families shown). Modified from Min et al. (2012), with permission. a. What type of graph is this? b. What do the upper and lower margins of the boxes indicate? c. Which male group had the highest median longevity? Explain your reasoning. 4.23 Pitcher plants of the genus Nepenthes are typically carnivorous, obtaining a great deal of their nutrition from insects that become trapped in the pitcher, die, and decay. N. lowii, a pitcher plant from Borneo, produces a second type of pitcher that attracts tree shrews, which provide nutrients by defecating into the pitcher while they feed on a substance secreted by the plant. Based on measurements of 20 plants, Clarke et al. (2009) calculated a 95% confidence interval for the mean fraction of total leaf nitrogen in the plant species derived from tree shrews: 0.57
