A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d = (blood pressure before taking new drug)-(blood pressure after taking new drug) . Use a significance level of a = 0.1 for the test. Assume that the systolic blood pressure levels are normally distributed for the population of patients both before and after taking the new drug. Patient 1 3 4 5 6 7 8 9 Blood pressure (before) 176 162 164 157 198 160 205 180 164 Blood pressure (after) 161 156 157 142 174 151 189 171 150 Copy Data
