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?

1. The number library books read in one semester by a group of 30 second graders is given in the table at the right. Create a reasonable frequency table for this data set with exactly 5 classes. Include a relative frequency column in the table. 39 52 59 45 48 48 56 78 63 58 64 43 20 72 39 59 67 66 55 68 27 63 69 67 60 57 48 36 49 56 2. Construct an ordered stem-and-leaf plot for the data given above in #8. Then, describe the shape of the distribution of the data set (either skewed left or skewed right or symmetric). (HINT: to keep appropriate spacing, choose Times New Roman font format for cells used to display the plot and begin each entry with an apostrophe to make the values act as text versus a single number.)
