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 college grade point average (GPA): y = 36 + 16x7 +52X2, where = job performance evaluation index, X4 = preemployment test score, x2 = college GPA. a) For an applicant who had a 2.8 GPA and scored 85 on the preemployment test, the forecast for the job performance index=(round your response to one decimal place). b) For an applicant who had a 2.5 GPA and scored 75 on the preemployment test, the forecast for the job performance index = (round your response to one decimal place)
