A regression equation is used to predict women's Weight (in pounds) from their Height (in inches). The correlation between Weight (W) and Height (H) turned out to be 0.70 . The average H was 64 inches and the average W was 119.6 pounds.
The regression equation turned out to be:
W(hat) = 30 + 1.4H
Now consider the regression equation to predict H from W using the same data set:
H(hat) = int + slope * W
where "int" and "slope" are some numbers. Find the value of "slope".
a. 0.00
b. 0.35
c. 0.55
d. 0.25
e. 0.71
