And find p value

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 0.05 signicance level. Is there sufficient evidence to support the claim that the drug is effective In lowering systolic blood pressure? Before 183 167 195 210 157 189 164 159 168 175 190 205 g After 144 177 176 179 152 155 146 163 169 162 184 143 @ In this example. pd Is the mean value of the differences d for the population of all pairs of data, where each individual difference d is dened as the systolic blood pressure reading before the drug was taken minus the reading after the drug was taken. What are the null and alternative hypotheses for the hypothesis test? A. Hoilldo Bi Hoid=o H1:pd=0 H11Pa0 H11Hd>0 Identify the test statistic. t= D (Round to two decimal places as needed.)
