Captopril is a drug designed to lower systolic blood pressure. In a trial, 12 randomly selected subjects were treated with the drug and another 12 randomly selected subjects were treated with the placebo. Assume the two populations are normally distributed. The results and some summary statistics are shown in the table. Note that some of the summary statistics may not be useful or relevant! Group Placebo Data 200 174 198 170 179 182 193 209 185 155 169 210 (21 = 185.3) |(s) = 17.1) Captopril (2 = 166.8) (s2 = 14.9) 191 170 177 167 159 151 176 183 159 145 146 177 4. 21 3 20 31 17 26 26 10 23 33 (d = 18.6) (s4= 10.1) II – II = P data Using a 0.01 significance level, is there sufficient evidence to support the claim that the mean systolic blood pressure is lower for those treated with the drug than for those treated with the placebo? Use the p-value method.
