Captoril 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 sign test and a 0.01 significance level to test if there is a sufficient evidence to support the claim that captoril has an effect on systolic blood pressure.
