To obtain some information, the teamsurveyed a simple random sample of 400 of the morethan 35,000 students attending the university. Eachstudent reported the average number of hours spentexercising each week and his or her perception of theeffect of exercise on stress level. The data in the tablebelow summarize the students' responses by averagenumber of hours exercising per week (less than 5, 5 to7, more than 7) and the perception of the effect ofexercise on stress level (positive, no effect, negative).Average Time Spent Exercising5 to 7 HoursLess Than 5Hours per WeekMore Than 7Hours per Weekper WeekPositive Effect8710235Perception of theEflect of Exercise onStress LevelNo Effect9536Negative Effect2013A chi-square test was used to determine if there is an association between the effect ofexercise on stress level and the average number of hours per week that students spentexercising.

A researcher is interested in hamster wheel-running activity during the summer versus the winter. She suspects that either the hamsters will run less during the winter to conserve energy or they will run more to keep warm. She records the activity of n = 25 hamsters during June, July, and August and compares their running-wheel revolutions per hour to the activity of the same hamsters during December, January, and February. The data are collected, and the results show an average difference score of MD = 5. 7 and a sum of squares of SS = 2,851.44. What is the value for degrees of freedom for this repeated-measures t test?
The authors of a paper compared two different instruments for measuring a person's capacity for breathing out air. (This measurement is helpful in diagnosing various lung disorders.) The two instruments considered were a Wright peak flow meter and a mini-Wright peak flow meter. Seventeen people participated in the study, and for each person air flow was measured once using the Wright meter and once using the mini-Wright meter. The Wright meter is thought to provide a better measure of air flow, but the mini-Wright meter is easier to transport and to use. Use of the mini-Wright meter could be recommended as long as there is not convincing evidence that the mean reading for the mini-Wright meter is different from the mean reading for Wright meter. For purposes of this exercise, you can assume that it is reasonable to consider the 17 people who participated in this study as representative of the population of interest. Data values from this paper are given in the accompanying table.…
