A study was conducted to test the effectiveness of a juggling class. Before the class started, six subjects juggled as many balls as they could at once. After the class, the same six subjects juggled as many balls as they could. The results are as follows. Student A B C D E F Before 3 4 3 2 4 5 After 4 5 6 4 5 7 a. Test whether the class is effective at increasing the number of balls they were able to juggle. Use a= 0.01 b. Construct a 99% confidence interval for the mean of the differences.
