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): = 33 +22x2 + 46X2, where y = job performance evaluation index, x1 = preemployment test score, x2 = college GPA. a) For an applicant who had a 2.8 GPA and scored 90 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 70 on the preemployment test, the forecast for the job performance index=(round your response to one decimal place)
