Question:
Using the following information, make a prediction for Y, given an X score of 8: Variable X: M = 12, SD = 3 Variable Y: M = 74, SD = 18 Pearson correlation of variables 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.
