1) You test a new drug to reduce blood pressure. A group of 15 patients with high blood pressure report thefollowing systolicpressures(measured in mm Hg): a) Calculate a 95% CI

for the change in blood pressure. b) Calculate a 99% 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 u= 0, and a = .05. Are the results consistent with (a)? Whyor why not? e) Finally, conduct a one sample t-test using u = 0, and a = .01. Are the results consistent with (b)?Why or why not?
