consider the fat set { 5, 6, 6, 7, 11, 12, 14, 15, 15, 15, 16, 17, 18, 19, 20, 20, 21}

a) construct the frequency distribution table for this data set consisting of five classes. use 5 as the lower limit of the first class. in addition to the class and frequency also include the class boundaries and relative frequencies of each class data in your table.

draw the frequency histogram based on the frequency distribution from (a).

c) draw the ogive based on the frequency distribution form (a).
