A student at a junior college conducted a survey of 20 randomly selected full-time students to determine the relation between the number of hours of video game playing each week, x, and grade-point average, y. She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is y = -0.0516x + 2.9389 (a) Predict the grade-point average of a student who plays video games 8 hours per week. The predicted grade-point average...
