A sample of 15 upper-class students who commute to classes was selected at registration. They were asked to estimate the distance (x) and the time (y) required to commute each day to class (see the following table).
a. Do you expect to find a linear relationship between the two variables commute distance and commute time? If so, explain what relationship you expect.
b. Construct a scatter diagram depicting these data.
c. Does the scatter diagram in part b reinforce what you expected in part a?
