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: 2.051E - 05 = 2.051*10⁻⁰⁵ and 5.944E - 18 = 5.944*10⁻¹⁸.
-Referring to Table 13-9, the degrees of freedom for the F test on whether HOURS affects SALARY are

• A) 1, 49.
• B) 1, 50.
• C) 49, 1.
