A health statistics center compiles data on the length of stay by ... a) what could be changed about these histograms to make them easier to compare? A. The vertical scales of both histograms could be reduced to 12. OB. The histograms could be combined so the data for men and women are mixed together. OC. The histograms could be put on the same horizontal scale, 0.0 to 20.0. D. The center could obtain data from four more women to match the sample sizes and add those data to the "Women" histogram. b) Describe these distributions by writing a few sentences comparing the duration of hospitalization for men and women. Choose the correct answer below. 4 OA. Lengths of men's stays appear to vary more than for women. Women have a mode near 5 days, with a sharp drop afterward. Men have a mode at about 12 days, with roughly equal amounts of times on either side of that mode. OB. Lengths of men's stays appear to vary more than for women. Men have a mode at 1 day and then taper off from there. Women have a mode near 5 days, with a sharp drop afterward. OC. Lengths of women's stays appear to vary more than for men. However, men appear to have a larger range of stay lengths than women. The distribution of women's stays appear to follow a bell curve. OD. Lengths of women's stays appear to vary more than for men. Men have a mode at 1 day and then taper off from there. The shapes of the distributions are roughly equal. c) Suggest a reason for the peak in women's length of stay. A possible reason is
