Quizplus · Accepted Answer

The regression formula is:

predicted college GPA = slope(hs GPA) + intercept

Substituting the given values:

predicted college GPA = 0.904(3.2) + 0.719 = 3.6118

Rounding off to two decimal places:

predicted college GPA = 3.61

Therefore, the predicted college GPA for a student with a high school GPA of 3.2 is 3.61, which is Option C.
