Men's Pre-Med 94 97 98 93 80 89 99 Ave=92.86 Var = 43.82 Men's Post-Med 90 91 89 88 81 80 92 Ave = 87.29 Var = 23.23 Women's Pre-Med 80 87 82 87 87 80 Women's Post-Med 78 85 78 79 85 80 Ave = 83.83 Ave = 80.83 Var = 12.60 | Var= 10.96 The Table above shows pre and post medication diastolic blood pressures for a group of 7 men as well as a group of 6 women. Whenever appropriate assume each column is a sample from a normal distribution. For all hypotheses testing questions state the hypotheses, find the test statistic, make a sampling distribution diagram shading the p-value, and then find the p-value in order to make a decision!
