Problem 3.8. Using the class data we collected at the
beginning of the semester you conducted a Regression study.
You used income as your dependent variable (Y) and you used age (X)
as your independent variable. You then obtained the
following:
Mean of X (X-bar) = 21.58 Standard Deviation of X
(Sx) = 6.31
Mean of Y (Y-bar) = 11,475 Standard Deviation of Y
(Sy) = 16,534
Coefficient of Correlation r = 0.4
Using your complete regression equation of the form Ŷ = a +
bX , what will be your estimated income if your age is
38.
