Test Individual Regression Coefficients for Significance
-Twelve nursing students are set to graduate and the registration clerk at the nursing school wonders if there is a correlation between a student's age, their GPA and their state board score. She collects data about the 12 students. The data is given below. Test the significance of the individual predictor variables at $\alpha = 0.05$.

A) Consider removing the variable "GPA" because it is not a good predictor of "State Board Scores".
B) Both explanatory variables have a significant linear relationship with the response variable.
C) Consider removing the variable "Age" because it is not a good predictor of "State Board Score".
D) Consider removing both variables because neither is a good predictor of"State Board Scores".
