You are given the following results on two variables X and Y:
` barx=36, bary=85, sigma_(x) =11`, Var (Y) = 64 and r (X, Y) = 0.66. Find the regression equations and estimate the value of x when y= 75.

Text Solution

Verified by Experts

The correct Answer is:
Regression equation of y on x : `y = 0.48x + 67.72`
Regression equation of x on y : `x=0.9y - 41.35`
When `y=75, x = 26.9`
