When subjects were treated with a​ drug, their systolic blood pressure readings​ (in mm​ Hg) 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 0.01 significance​ level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic blood​ pressure?   Before 169 205 188 183 167 164 157 175 188 158 189 159   After 186 143 184 144 177 188 152 162 179 159 155 163
