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)

To find the slope for the regression equation, we need to use the formula:

slope = SP / SSx

Given that SSx = 10 and SP = 8, the slope will be:

slope = 8 / 10

Therefore, the correct answer is option a. 8/10.

For the regression equation Y = bX + a, any X,Y point that lies on the regression line will satisfy this equation. Therefore, the correct answer is option b. b,a.

To find the slope for the regression equation, we can use the formula:

slope = SP / SSx

In this case, the SSx is given as 10 and the SP is given as 8. So, substituting these values into the formula:

slope = 8 / 10

Simplifying the expression:

slope = 4 / 5

Therefore, the slope for the regression equation is 4/5.

For the second question, to determine which X,Y points will be on the regression line, we need to consider the form of the regression equation Y=bX+a. In this equation, 'a' represents the Y-intercept and 'b' represents the slope.

The correct answer would be option b. b,a.

In the regression equation, Y=bX+a, the points on the regression line would be represented as (X, Y), where Y is equal to b times X plus a. So, the correct option would be b,a.
