Question 3: Data on the total tobacco exposure time (in seconds) for G-rated animated films with tobacco use released between 1937 and 1997 produced by Walt Disney, Inc. are as follows: 223 176 548 37 158 51 299 37 11 165 74 92 6 23 206 9 Similar data for G-rated animated films with tobacco use produced by MGM/United Artists, Warner Brothers, Universal, and Twentieth Century Fox are as follows: 205 162 6 1 117 5 91 155 24 55 17 (a) (4 marks). Construct a comparative (back-to-back) stem-and-leaf plot to compare the two exposure-time distributions. Use hundreds for stems and tens (truncated) for leaves. Divide each stem into a "Low" and "High" part. (b) (4 marks). Compare the two exposure-time distributions with respect to shape, centre, spread and outliers.
