Question

A linear regression equation has b = 3 and a = - 6.What is the predicted value of Y for X = 4?
A)Ŷ = 6
B)Ŷ = - 21
C)Ŷ = - 2
D)cannot be determined without additional information

Quizplus · Accepted Answer

The predicted value of Y is calculated using the equation Ŷ = a + bX. Substituting the given values, Ŷ = -6 + 3(4) = 6.
