12 17 17 16 16 17 15 13 13 14 

 

construct a frequency distribution, letting each class have a width of one

Answer 1

A frequency distribution is a count of how many data points are in each class.  For example, 12 appears 3 times so its frequency is 3.  The sum of all the frequencies should equal the total number of data points which is 40.
