Question

If regression coefficient of y on x is -1.4 and correlation coefficient between x and y is -0.87, the value of regression coefficient of x on y will be;
​

Answer 1

Answer:

Find the mean of all the x-values.

Find the standard deviation of all the x-values (call it sx) and the standard deviation of all the y-values (call it sy). ...

For each of the n pairs (x, y) in the data set, take.

Add up the n results from Step 3.

Divide the sum by sx ∗ sy.
