Suppose that a polling company surveyed 600 people about how much time they spend reading each week. The results of this survey were compiled and used to create this relative frequency histogram. Relative frequency (%) 30- 20- 10- 0 30 90 120 150 180 210 240 270 Weekly minnes of reading Assume that all percentages shown in the histogram are whole numbers. Each of the hars 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 read less than 90 minutes per week? 63 0 How many respondents said that read between 60 and 120 minutes per week?
