The following histograms represent the heights, measured to the nearest cm, of 14 women and 13 men. Women's heights 3- 2- 1 150 155 160 165 170 175 180 185 190 Height (cm) Men's heights 2 1 0+ 150 155 160 165 170 175 180 185 190 Height (cm) Choose the two options from the list below that are true. Select one or more: Each of the intervals with the lowest frequency in the women's heights dataset contains a smaller number of data values than one of the intervals with the lowest frequency in the men's heights dataset. The histograms are divided into six intervals for the women's heights dataset and eight for the men's heights dataset. The histogram of the women's heights dataset has a greater number of intervals containing two values than the histogram of the men's heights dataset. Both histograms are right-skewed. O The range of the women's heights dataset is greater than the range of the men's heights dataset. Aouan ba Aouan ba

Given the following histogram for a set of data, how many values in the data set are greater than 10.5 but less than 12.5? A histogram has a horizontal axis labeled Values from 7.5 to 16.5 in increments of 1 and a vertical axis labeled Frequency from 0 to 6 in increments of 1. The histogram has vertical bars of width 1, starting at the horizontal axis value of 7.5. The approximate heights of the bars are as follows, where the horizontal axis label is listed first and the approximate height is listed second: 7.5, 1; 8.5, 2; 9.5, 3; 10.5, 2; 11.5, 3; 12.5, 4; 13.5, 1; 14.5, 5; 15.5, 6.
