a. Construct a scatter plot. Choose the correct graph below.

01000200TrailerViews(mil)OpeningGross($mil)

A scatter plot has a horizontal axis labeled Trailer Views in millions from 0 to 100 in increments of 10 and a vertical axis labeled Opening Gross in millions of dollars from 0 to 200 in increments of 20. About 60 plotted points follow the general pattern of a line segment that rises from left to right from (1, 1) to (54, 66), before following the general pattern of a line segment that rises from left to right at a sharper rate to (61, 107). The points (79, 143) and (84, 175) are also plotted. All coordinates are approximate.
