Thirty college students were recruited to participate in a research study on the effects of exercise on class attendance. The researcher tells them the study is about the effect of exercise on diet and sleep (i.e., deception). She has them monitor their diet, sleep, and attendance for the week prior to beginning the exercise program and then again for week after the program has been underway for 2 weeks. She wants to compare the number of absences reported before the program began to the number of absences after the program began for each participant to find out whether the exercise program had an effect. a. What type of test should be used to analyze her data? i. Z-test ii. Single-sample t-test iii. Independent-measures t-test iv. Repeated-measures t-test b. What would the hypotheses be?
