Question

Use the following data to a. determine the coefficient of correlation, rounded to the nearest thousandth, b. find the equation of the regression line for time watching TV and time on the Internet, c. approximate how much time on the Internet can we predict for a person who spends 10 hours weekly watching TV.

Subject: A B C D E F G
Time watching TV: 8, 4, 2, 7, 7, 5, 6
Time on the internet: 14, 12, 8, 17, 18, 9, 18 

A. a. r = 0.752 b. y = 1.52x + 5.25 c. 20.5 hours
B. a. r = -0.752 b. y = -1.52x + 5.25 c. 9.9 hours
C. a. r = -0.752 b. y = 5.25x + 1.52 c. 54 hours
D. a. r = 0.752 b. y = 1.52x - 5.25 c. 10 hours
