The data show systolic and diastolic blood pressure of certain people.

The data show systolic and diastolic blood pressure of certain people. Find the regression equation, letting the systolic reading be the independent (x) variable. Find the best predicted diastolic pressure for a person with a systolic reading of137. Is the predicted value close to 72.0, which was the actual diastolic reading? Use a significance level of 0.05.
