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
8/10
To find the slope for the regression equation, we need to calculate the covariance (SP) and the variance (SSx). The formula for the slope of the regression equation is:
slope = SP / SSx
In this case, we are given that SP = 8 and SSx = 10.
Thus, the slope for the regression equation is:
slope = 8 / 10
which simplifies to:
slope = 4 / 5
Therefore, the correct answer is:
a) 8/10
