Question

Given that the systolic blood pressure in the right arm is 90 mm Hg, the best systolic blood pressure in the left arm is how many mm Hg?

Listed below are systolic blood pressure measurements (in mm Hg) obtained from the same woman. Find the regression equation, letting the right arm blood pressure be the predictor (x) variable. Find the best predicted systolic blood pressure in the left arm given that the systolic blood pressure in the
right arm is 85 mm Hg. Use a significance level of 0.05.

The regression equation is y = 76.8 + 0.9 x.
(Round to one decimal place as needed.)
