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 85 mm Hg. Use a significance level of 0.05.
Right Arm 
103 
102 
95 
75 
74 


Left Arm 
174 
167 
151 
148 
148 
The regression equation is y=92.8p+0.7x.
(Round to one decimal place as needed.)
Given that the systolic blood pressure in the right arm is 85mm Hg, the best predicted systolic blood pressure in the left arm is _______
(Round to one decimal place as needed.)
The statistical software output for this problem is:
p  Value for slope = 0.066
This p  value is greater than 0.05 so we do not reject the null hypothesis. Hence,
Best predicted left arm blood pressure
= Average of all y values
= (174 + 167 + 151 + 148 + 148)/5
= 788/5
= 157.6
