In a statistics course, a linear regression equation was computed to predict the final-exam score from the score on the first test. The equation as ŷ = 10 +0.75x where y is the final-exam score and x is the score on the first test. Parvez scored 80 on the first test. What is the predicted value of the Parvez's score on the final exam? Parvez scored 60 on the final exam. What is the value of the residual?
