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

90mm Hg. Use a significance level of 0.05.

right arm	100	99	91	76	77
left arm	175	170	146	148	147

the regression equation is y= ___ + ___x

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.
