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 ModifyingAbove y with caret equals negative 0.0592 x plus 2.9306y=−0.0592x+2.9306. (a) Predict the grade-point average of a student who plays video games 8 hours per week. The predicted grade-point average is 2.462.46. (Round to the nearest hundredth as needed.) (b) Interpret the slope. For each additional hour that a student spends playing video games in a week, the grade-point average will decrease by . 0592.0592 points, on average. (c) If appropriate, interpret the y-intercept.
