The data show systolic and diastolic blood pressure of certain people. Find the regressionequation, letting the systolic reading be the independent(x) variable. Find the best predicted diastolic pressure for a person with a systolic reading of 146. Is the predicted value close to 94.0, which was the actual diastolicreading? Use a significance level of 0.05.
Systolic Diastolic
120 61
119 88

What is the regressionequation?
y =___+___x
(Round to two decimal places asneeded.)
What is the best predicted diastolic pressure for a person with a systolic reading of 146?
