- The graphs below show the scores students in an advanced statistics course received for homework completed and for the subsequent midterm exam. Homework scores are based on assignments that preceded the exam. The maximum homework score a student could obtain was 500 and the maximum midterm score was 350. The original score for student 10 was 234 (the lowest) for the homework and 125 (the lowest) for the exam. After the student reviewed the exam, she discovered that only a third of the problems had been graded and she subsequently received a score of 348 (the highest).

In an attempt to verify his claim, Mackowiak, Wasserman, and Levine22 took temperatures from 148 healthy peopleover a 3-day period. A data set closely matching the one in Mackowiak’s article was derived by Allen Shoemaker, and appears in the Journal of Statistics Education.23 The body temperatures for these 130 individuals are shown in the relative frequency histogram that follows. See Attachment a. Describe the shape of the distribution of temperatures.b. Are there any unusual observations? Can you think of any explanation for these?c. Locate the 98.6-degree standard on the horizontal axis of the graph. Does it appear to be near the center of the distribution?9. For questions 9.1-9.5, refer to the following problem. A fitness trainer developed a set of breathing exercises aimed to improve one's speed. To test these new exercises, this trainer randomly selected 12 from his regular clients and asked to run a total distance of 2 km. The next day, he asked the same respondents to undergo his breathing exercises and run a total distance of 2 km afterwards. He recorded the total time (in minutes) of his 12 clients from both runs (data given in the table below). At 1% level of significance, is there sufficient evidence to conclude that these new breathing exercises enhance one's speed? 9.1. Which type of sampling was used?
