The clerical staff is almost entirely female, while a majority ofthe production workers and technical staff are male. As a result, the distributions of salaries formale and female employees may be quite different. The table below gives the frequencies andrelative frequencies for women and men. Make histograms from these data, choosing the typethat is most appropriate for comparing the two distributions. Then describe the overall shapeof the two salary distributions and the chief differences between them.Salary Women Men($1000) Number % Number %10–15 89 11.8 26 1.115–20 192 25.4 221 9.020–25 236 31.2 677 27.925–30 111 14.7 823 33.630–35 86 11.4 365 14.935–40 25 3.3 182 7.440–45 11 1.5 91 3.745–50 3 0.4 33 1.450–55 2 0.3 19 0.855–60 0 0.0 11 0.460–65 0 0.0 0 0.065–70 1 0.1 3 0.1Total 756 100.1 2451 100.0
