Please find the test statistic and p-value.

Please find the test statistic and p-value. When subjects were treated with

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 177 188 159 183 167 195 155 210 169 175 157 158 After 161 179 163 144 177 176 156 179 186 162 152 187 In this example, u is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined 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. Ho: Hd = 0 OB. Ho: Ha # 0 H1 : Pd >0 H 1 : Hd = 0 OC. Ho: Ha = 0 OD. Ho: Ha # 0 H1: Ha 0 Identify the test statistic. t= (Round to two decimal places as needed.)
