The data show systolic and distolic blood presure of certain people. Find the regression equation, letting the first variable be the independent (x) variable. Find the best predicted diastolic pressure for a person with a systolic reading of 111. Use the significance level of 0.05.
Systolic: 142, 114, 114, 133, 148, 143, 116, 116
Diastolic: 79, 86, 61, 71, 82, 79, 87, 58
