Question
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 = -0.0552x +2.9446.
(a) Predict the grade-point average of a student who plays video games 8 hours per week.
The predicted grade-point average is 2.50
(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
by
points, on average.
