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.

Step-by-step explanation:

given that 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.

x=number of hours of video game playing each week

y= grade-point average,

The regression line found out using least squares method is

a) The grade-point average of a student who plays video games 8 hours per week.

=

2.45844 is the answer.

Round off to 2.46

b) Slope = -0.0592 means For each additional hour that a student spends playing video games in a week, the grade-point average will decrease by . 0592. points, on average

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

b.my answer is b.
