In a social work research class, the instructor asked each student how many hours he or she had studied for a test and then compared this (predictor) variable with his or her test grade (the outcome variable). Data analysis produced a high positive correlation and the regression equation Y' = 55 + 6(X). Mark was sick when the exam was given. He studied 5 hours prior to taking the make-up test. What is Mark's predicted grade on the test?
A) 61

Using the regression equation Y' = 55 + 6(X):
Y' = 55 + 6(5)
Y' = 85
