Construct a percent frequency polygon of the perceived age estimates. Use the classes of Exercise 2.71.
In Exercise 2.71
Consider constructing a frequency distribution and histogram for the perceived age estimates.
a. Develop a frequency distribution, a relative frequency distribution, and a percent frequency distribution for the perceived age estimates using eight classes each of length 2.while the procedure presented in Section 2.2 would tell us to use six classes, in this case we get a more informative frequency distribution by using eight classes.
b. Draw a percent frequency histogram for the perceived age estimates.
c Describe the shape of the distribution of perceived age estimates.
