Ten clients were timed for the mile before and after the class. Their times, in minutes, are shown in the table above. We want to test to see if the class improves the client's times. If you find differences, used = before - after. The test statistic and p-value are, respectively: O .9936,.1681 O None of the above 2.26, .0119 O 2.14,.0160 O 2.24,.0306Client Client Client Client Client Client Client Client Client Client 1 2 3 4 5 6 7 8 9 10 Before 8.5 15 12 10 8 11 10 After 8 12 11 9.5 9.5 8 9 9 8.5 A local health club offers a class that helps clients improve their jogging times for the mile.
