- Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram. Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?arrow_forwardThe IQ scores of 50 students are given below. 85 85 85 86 87 87 88 89 89 90 90 91 93 93 95 98 99 99 100 100 101 101 102 103 106 106 107 109 111 111 112 112 112 112 113 113 113 114 114 115 115 116 117 118 119 119 119 85 - 89 90 95 (a) Construct a grouped frequency distribution for the data.
