Using the following information, complete the following:
Variable X: M = 12, SD = 3
Variable Y: M = 74, SD = 18
Pearson correlation of variables X and Y = 0.46
a. Calculate the y intercept, a.
b. Calculate the slope, b.
c. Write the equation for the line.
d. Draw the line on an empty scatterplot, basing the line on predicted Y values for X values of 0, 1, and 18.
