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

 Right Ar Left Arm 103 102 95 80 81 176 169 145 145 147

The regression equation is y equals=.
___ +__ x.

(Round to one decimal place as needed.)

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.

The statistical software output for this problem is: Hence,

Regression equation:

y = 54.4 + 1.1 x

p - value is greater than 0.05 so the model is not significant. Hence,

Best predicted value = Average of y values = 156.4
