Lately I have shifted to authoring web pages using XHTML5. I hand code all of my web pages with a text editor. The XHTML5 pages appear to contain more characters than HTML pages. The table includes data on the number of characters in my most recent HTML and XHTML web pages. As part of a study to determine whether XHTML pages contain more characters I gathered the following data on recently written web pages.

Sums:
1. Sketch a relative frequency histogram of the data, labeling your horizontal axis and vertical axis as appropriate.
2. __________ What is the shape of the histogram?
3. p(characters ≤ 5600) = __________ What is the probability that a recently written web page has 5600 characters or less?
4. p( 15800 < characters ≤ 19200) = __________ What is the probability that a recently written web page has more than 15800 characters and less than 19200 characters?
5. __________ What shape might a one sided die have?
