SCENARIO 13-9
It is believed that, the average numbers of hours spent studying per day (HOURS) during undergraduate education should have a positive linear relationship with the starting salary (SALARY, measured in thousands of dollars per month) after graduation. Given below is the Excel output for predicting starting salary (Y) using number of hours spent studying per day (X) for a sample of 51 students. NOTE: Only partial output is shown.

Note: 2.051 E - 05 = 2.051*1 0-5 and 5.944 E -18 = 5.944 *10 -18 .
-Referring to Scenario 13-8,what is the predicted value of GPA when ACT = 20?
A)2.61
B)2.66
C)2.80
D)3.12
