Question

very unsure of my answers

The accompanying histograms show the number of pairs of shoes reported for 309 males and for 294 females. Descriptive statistics are also shown. Complete parts (a) through (d) below. Variable Female Male N 294 309 Mean StDev Minimum 28.25 21.94 1.00 12.314 13.038 1.000 Q1 Median 9.00 22.00 3.000 4.000 Q3 Maximum inte range 36.00 100.00 27.00 12.000 100.000 9.000 Click the icon to view the histograms of the number of pairs of shoes for men and women. a. Describe the shape of each histogram. The histogram for the men's distribution of data is strongly right-skewed. The histogram for the women's distribution of data is strongly right-skewed. b. Because of the shapes, what measures of the center should be compared, the means or the medians? Because of the shapes of the distributions, the men's measure of center, the median, should be compared to the women's measure of center, the median. c. Because of the shapes, what measure of spread is preferred, the standard deviation or the interquartile range? Because of the shapes of the distributions, the preferred measure of spread for the men is the interquartile range, and the preferred measure of spread for the women is the interquartile range. d. Compare the centers and spreads in context. The median of 309 pairs of shoes for men is lower than the median of 294 pairs of shoes for women. The interquartile range of 309 pairs of shoes for men is lower than the interquartile range of 294 pairs of shoes for women. (Type integers or decimals. Do not round.)
