Question

A set of X and Y scores has SSx=10, SSY=20, and SP=8, what is the slope for the
regression equation?
a. 8/10
b. 8/20
c. 10/8
d. 20/8

For the regression equation, Y=bX+a, which of the following X,Y points will be on the
regression line?

a. a,b
b. b,a
c. 0, a
d. 0, b
For the second question, look at c.

For the first question, look at a.
b = SP/SSx (covariation/variation in x)
