a. Construct a frequency distribution using 7 classes. Let your lowest class limit for the first class be the smallest number in the data set. Show how you calculate the class width then round the calculated class width to the nearest whole number. Use that number as the class width.

Class Width:

b. Use the frequency distribution to construct a frequency polygon of the data. Graph should be done on thegrid paperprovided (or your own). Please include appropriate title and labels. [2 pts]

c. Use the frequency distribution to construct a histogram of the data. Graph should be done on thegrid paperprovided (or your own). Please include appropriate title and labels.

1. Construct an Ogive of the data. Graph should be done ongrid/graph paperand properly labeled. [2 pts]
2. Based on the graphical description of the data that you created in part c, what is the general shape of the distribution-uniform, symmetric, left skewed or right skewed?
