Question

Every morning, Tania leaves for work a few minutes after 7:00 A.M.. For eight days, she keeps track of the time she leaves (the number of minutes after 7:00) and the number of minutes it takes her to get to work. Following are the results:

Time Leaving:                 13  14  16  30  20  12  9  17  16  10  16

Lenght of Commute:      27  20  23  45  20   45 20  28  27  23  30

a. Construct a scatterplot of the lenght of commute (y) versus the time leaving(x).

b. Compute the least-squares regression line for predicting the length of commute from the time leaving.

c. Compute the coefficient of determintion.
