C) 6 subjects were given a drug to dull pain. Their reaction time to a shock stimulus was measured (in ms). Prior to treatment: 91, 87, 99, 77, 81, 91, 75 After Treatment: 91, 99, 103, 111, 99, 104, 102 -First state the null and alternative hypothesis. -Did the drug increase the resistance to pain (assume the data is normally distributed)? -Did the drug increase the resistance to pain (assume the data is not normally distributed)?

D) You are asked to compare the average wing size (in cm) of two groups of Drosophila melanogaster. The first group consists of Drosophila from brazil; the second group is North America Drosophila. The data are given below. Brazilian = 18, 22, 21, 17, 20, 17, 23, 20, 22 ,21 North America = 16, 17, 14, 21, 19, 18, 13, 15, 17, 21 -First state the null and alternative hypothesis. -Is the wing size equal in both groups (assume the data is normally distributed and the variances are equal)? -Is the wing size equal in both groups (assume the data is not normally distributed)?
