Multiple Choice

A large pharmaceutical company selected a random sample of new hires and
Obtained their job performance ratings based on their first six months with the company.
These data were used to build a multiple regression model to predict the job performance
Of new hires based on age, GPA and gender (female = 1 and male = 0) . The regression
Equation is: $$\text { Job Performance } = - 60.8 + 4.80 \text { Age } + 1.44 \text { GPA } + 9.06 \text { Gender. }$$
Which of the following is the correct interpretation for the regression coefficient of
Gender?

• A) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 points higher than for males of the same age and GPA.
• B) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 points lower than for males of the same age and GPA.
• C) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 times higher than for males.
• D) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 times lower than for males.
• E) The regression coefficient is not significantly different from zero.
