1) You test a new drug to reduce blood pressure. A group of 15 patients with high blood pressure report the following systolic pressures [measured in mm Hg): .17 5 before medication: 186119150 142 15916? 180 196 132 127 129 194129 146 192 156.53 27.409 after medication: 185118141114515316617719513.3125 131 192128144189 155.41I 26.691 change: 1 1 3 -3 2 1 3 1 -l 2 -2 2 l 2 3 1.06? 1.3915 a} Calculate a 90% CI for the change in blood pressure. b) Calculate a 99.9% CI for the change in blood pressure. c} Does either interval (the one you calculated in (a) or {b)} include 0'? Why is this important? d) Now conduct a one sample t-test using pt = 0, and n = .10. Are the results consistent with (a)? Why or why not? e} Finally. conduct a one sample t-test using ,n = 0. and a = .001. Are the results consistent with (b)? Why or why not? [Make sure you answer the part in hold for (d) and (e).
