For the scenario described below, simply name the procedure that is appropriate to answer the question. For example,
1-proportion z-interval or chi-square goodness of fit test. Do NOT carry out the procedure.
-In a study on insomnia in men over the age of 65, it is found that exercise may play a role in sleep. The researchers assign a group of 100 men to exercise for a month, while another
100 volunteers are asked to abstain from most exercise. At the end of the month, the exercise group had 23 out of 100 men with difficulty in sleeping, whereas the non-exercise group had 31 out of 100. Does this provide statistically significant that exercise improves sleep for men over 65?
