Question

solve for sytolic standing and sitting

 

Perform a t-test (significance level a = 0.05) to test your null hypothesis and compare diastolic blood pressure values measured in the sitting down and standing up position. Do the same for the mean systolic pressure measurements. Enter the degrees of freedom, t-values and p-values for both tests in the table below. Provide all values to 3 significant figures. Hint: Use a paired t-test.
