Exercises 23–26 refer to the tables and relative frequency distributions associated with Exercises 1–4.
Weather Reports Use the data in Table 13.
(a) For what percentage of the 60 minutes from 5 a.m. to 6 a.m. are there either fewer than 22 or more than 27 visits to the weather page?
(b) For what percentage of the hour are there between 23 and 25 visits (inclusive)?
(c) Draw the relative frequency histogram.
(d) What would be your estimate of the average number of visits during a minute of the hour for which the data has been tabulated? Explain.
