For this series of questions, you will conduct a variance ratio F test and a two-tailed homoscedastic t test on the following data sets: Set A: 17, 13,21, 15, 17, 21, 22 Set B: 10,17, 12, 15,17, 19, 15 You will be asked: (a, 3 pts) What is the test statistic for the preliminary F-test? (b, 5 pts) What is the calculated t value? (c, 2 pts) Select the best conclusion for your test from an array of choices. (provide answers to a-b to the closest 0.001 and provide the absolute value of the calculated t value)
