Question 2 Do running times of American movies differ somehow from running times of French movies? A researcher investigated this question by randomly selecting 25 recent movies of each type, resulting in the following running times: Am: 94 90 95 93 128 95 125 91 104 116 162 102 90 110 92 113 116 90 97 103 95 120 109 91 138 Fr: 123 116 90 158 122 119 125 90 96 94 137 102 105 106 95 125 122 103 96 111 81 113 128 93 92 Construct a comparative stem-and-leaf display by listing stems in the middle of your paper and then placing the Am leaves out to the left and the Fr leaves out to the right. Then comment on the interesting features of the display.
