Question:

A multiple-regression equation with two predictor variables produces R2 = .22.
a. If SSY = 20 for a sample of n = 18 individuals, does the equation predict a significant portion of the variance for the Y scores? Test with α = .05.
b. If SSY = 20 for a sample of n = 8 individuals, does the equation predict a significant portion of the variance for the Y scores? Test with α =.05.
