Solve for the following problems with the appropriate type of non-parametric test.
1. Captopril is a drug designed to lower systolic blood pressure. When subjects were treated with this drug, their systolic
blood pressure readings (in mm Hg) were measured before and after the drug was taken. Use a 0.05 significance level, is
there significant evidence to support the claim that captopril influences systolic blood pressure?
