Question: A professor used data from last semester's statistics class to create a regression that predicts how students will do on the final exam. The equation is yˆ = 70.2 + 3.2 (X1) - 6(X2), where X1 is the number of hours studied for the exam and X2 is the number of sleep interruptions the night before the exam. What is the predicted score of:
a) a student who studied for 10 hours and had 2 sleep interruptions?
b) a student who studied for 6 hours and had no sleep interruptions?
