The least-squares regression line that describes this relation is y 0.0593x 2.9263. (a) Predict the grade-point average of a student who plays video games 8 hours per week. The predicted grade-point average is 2.45 (Round to the nearest hundredth as needed.) (b) Interpret the slope. by points, on average.

Explanation / Answer

we are given the equation as y = -0.0593x+2.9263 , putting x = 8 in the equation we see

y = -0.0593*8+2.9263

y = 2.4519

now the second question is about interpretation of the slope

y = -0.0593*x+2.926 , so for each additional unit change in x , the y would decrease by -0.0593 units .

Decrease because the slope is negative
