1. Conduct a one sample T test to investigate whether the average systolic blood pressure is equal to the historical control 110 mm Hg.
(Show your work. And attache your SAS output if needed)
1) Calculate the point estimate (average systolic blood pressure)
2) Calculate standard error
3) Calculate the test statistics
4) Find the critical value
5) Find the p value
6) Interpret the result from t test statistics
2. Construct and interpret the 95% confidence interval to estimate the average systolic blood pressure
(Show your steps to construct the 95% confidence interval)
3. State conclusion for the study
