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)
