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.  Construct a 95% prediction interval for the State Board Score a student will get if the student's age is 24.

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

◦ The result is not reliable because the predictor variable is not a good indicator of the State Board Score.
◦ (542.5, 608.6)
◦ (561.30, 587.30)
◦ (527.93, 620.67)
