1.Construct a frequency distribution for the data set using the indicated number of classes. In the table, include the midpoints, relative frequencies, and cumulative frequencies. Which class has the greatest frequency and which has the least frequency? Draw frequency histogram, relative frequency polygon and cumulative frequency ogive plots for each of the data sets.
