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.

Based on the results from your t-tests, do you think that a change in posture has a relevant (statistically
significant) effect on diastolic or systolic blood pressure?
