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

Right Ar	103	102	95	80	81
Left Arm	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.

Answer 1

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
