Question

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 90 mm Hg. Use a significance level of 0.05.

a. The regression equation is

y= 
​(Round to one decimal place as​ needed.)
 
b. Given that the systolic blood pressure in the right arm is
90 mm​ Hg, the best predicted systolic blood pressure in the left arm is
 
 
mm Hg.
​(Round to one decimal place as​ needed.)
