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".
