Use the following to answer the question(s) below.
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 results of the analysis are shown below.
-Based on the F-statistic and associated P-value, we can conclude that at α = 0.05
A) The regression equation is not significant.
B) All independent variables in the model are significant.
C) The regression model is significant overall.
D) None of the independent variables in the model are significant.
E) All independent variables in the model are significant and the regression equation is significant.

The F-statistic and associated P-value suggest that the regression model is significant overall, meaning that at least one independent variable is significantly related to job performance. However, we cannot determine which specific variables are significant without examining their individual coefficients and associated P-values.
