Using the following information make a prediction fro y, given an x score of 8

Variable X: M=12, SD= 3

variable Y: M=74, SD= 18

Pearson correlation of variable x and y = 0.46

a. transform the raw score for the independent variable to a z score.

b. calculate the predicted z score for the dependent variable.

c.Transform the z score for the dependent variable back into a raw score.

d. calculate the y intercept, a.

e. calculate the slope, b.

f. write the equation for the line.

g. Draw the line on an empty scatterplot, basing the line on predicted y values for x values of 0, 1 and 18
