a) Build a table for the frequency distribution that has sixteen class intervals of width 1 inch. Utilize 61.5 inches as the lower limit of the first interval and 62.5 as the upper limit
b) Add a column of relative frequencies of the table found in (a)
c) Add a column of cumulative relative frequencies to the table found in (a)
