When subjects were treated with adrug, their systolic blood pressure readings(in mmHg) were measured before and after the drug was taken. Results are given in the table below. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Using a 0.05 is there sufficient evidence to support the claim that the drug is effective in lowering systolic bloodpressure?
