An experiment is conducted to determine whether intensive tutoring (covering a great deal of material in a fixed amount of time) is more effective than paced tutoring (covering less material in the same amount of time). Two randomly chosen groups are tutored separately and then administered proficiency tests. The data collected and summarized below: Group1 (the intensive group) consisted of 15 students and resulted in an average grade of 49.55 with a standard deviation of 10. group 2 (the paced group) consisted of 17 students and resulted in an average grade of 42.29 with a standard deviation of 6.52. Assume that the population variances of both groups are different. Find the test statistic to test if intensive tutoring is more effective than paced tutoring at the significance level of 0.01.
