Jose wanted to see if running three times a week would improve mile times for students in his gym class. . . . . The other 15 students did their normal gym class for 4 weeks. At the end of four weeks, both groups ran a mile. The average time for the students that ran 3 times a week was 7 minutes. . The average time for students who did the normal gym class was 8 minutes. What conclusion can you make? . He took a random sample of 30 students. All 30 students ran a mile and their time was recorded. Fifteen students were randomly assigned to run a mile- three times a week for 4 weeks. . Since the difference in times was only one minute, we can make the conclusion that running a miles three times a week did not improve mile time. No conclusion, the difference was not large enough to say that running a miles three times a week helped. No conclusion, the sample was not large enough to make a conclusion on whether or not running a mile helped. Since the difference was fairly large, one minute, we can make the conclusion that running a mile three times a week does improve mile time.
