You have been hired as the Media Librarian for the Johnson City Public Library and the Associate Director tells you that they are thinking of reducing the lending period for audio books from the current 21 days. You are asked for your input, so you take a random sample of 48 of the titles and obtain the duration in days that each was checked out the last time. The results are:

9,9,10,10,10,10,12,12,12,12,12,12,12,13,13,13,13,13,13,14,14,14,14,14,14,14,14,14,14,15,15,15,15,15,15,15,18,18,18,18,19,19,20,22,22,23,23,24

Assemble a presentation of the data including mean, mode, median, and standard deviation. Assemble a histogram or frequency polygon of the data.

What percentage of items circulate between 11.06 and 15.57 days?

If these sample items represent the population and the lending period was reduced to 14 days, what percent of the circulation would be impacted?

The Associate Director states in a meeting that, "The typical audio book circulates for more than 13 days." The Director asks you if that is true. What percent of items circulate for less than 13 days?
