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?
