Question

A set of n = 15 pairs of X and Y scores has SSX = 10, SSY = 40, and SP = 30. What is the slope for the regression equation for predicting Y from X?​

Answer 1

3

Explanation:

We have given
`SS_X=10`,
`SS_Y=40` and SP =30

We have to find the slope for regression on Y from X

The slope on Y from X is given by
`b_(yx)=(SP)/(SS_X)`

As we have given the value of SP =30 and value of
`SS_X=10`

So slope for regression will be
`b_(yx)=(30)/(10)=3`
