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

Age	GPA	State Board	Age	GPA	State Board
26	3.0	620	27	3.3	639
25	3.1	568	25	3.5	558
30	2.3	633	26	2.0	595
20	2.5	516	20	3.2	511
23	3.9	585	25	3.5	579
23	2.5	584	23	4.0	566

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