A professor wanted to find a linear model that relates the number of hours a student plays video games each week, h, to the cumulative grade-point average, G, of the student. He obtained a random sample of 10 full-time students at his college and asked each student to disclose the number of hours spent playing video games and the student's cumulative grade-point average. Complete parts (a) through (f) below. Hours of Video Games per Week, h 2. 2 4 5 5 5 7 10 10 12 14 Grade-point Average, G 3.19 2.75 3.44 2.52 3.39 2.48 2.51 2.24 1.73 2.21 D The number of hours is being used to predict Cumulative grade-point average. (b) Use a graphing utility to draw a scatter diagram. Choose the correct scatter diagram below. O A. B. OC OD. 00 B 00 ロロ 0 8 B O 8 8 Do B 00 27 [-15,0,1] by [0,5,1] [0,15,1] by [0,5,1) [-15,0,1] by [-5,0,1] [0,15,1] by [-5,0,1) (c) Use a graphing utility to find the line of best fit that models the relation between the number of hours of video game playing each week and grade-point average. Express the model using function notation G0 G(h) = (Type an expression using h as the variable. Round to four decimal places as needed.)
