Question (2) A researcher wanted to find the effect of a special diet on systolic blood pressure. She selected a sample of seven adults put them on this dietary for 3 months. The following table gives the systolic blood pressures of these seven adults before and after the completion of this plan. Before 210 180 195 220 231 199 224 After 193 186 186 223 220 183 233 Let ud be the mean reduction in the systolic blood pressures due to this special dietary plan for the population for all adults. Construct a 95% confidence interval for Ud. Assume that the population of paired differences is approximately normally distributed.
