The following multiple regression model was developed to predict job performance as measured by a company job performance evaluation index based on a preemployment test score and col grade point average (GPA): where y job performance evaluation index, y=39+ 19x +53x2 = X preemployment test score, X2=college GPA. a) For an applicant who had a 3.2 GPA and scored 85 on the preemployment test, the forecast for the job performance index = 1823.6 (round your response to one decimal place). b) For an applicant who had a 2.5 GPA and scored 70 on the preemployment test, the forecast for the job performance index= (round your response to one decimal place).
