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 significance level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic blood pressure? Before 175 169 159 166 155 157 172 177 158 183 189 167 After 162 186 163 167 156 152 172 190 159 144 155 177 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? O A. Ho: Hd = 0 OB. Ho: Ha # 0 H1: Hd 0 &C. Ho: Hd = 0 OD. Ho: Ha #0 H1:Ha >0 H1 : Pd = 0 Identify the test statistic. 1=(Round to two decimal places as needed.) Enter your answer in the answer box and then click Check
