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 
103

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
