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 = 38 + 16*, + 46*2. where y= job performance evaluation index, *, = preemployment test score, *2 = college GPA. a) For an applicant who had a 3.0 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)
