Answer

a) This histogram shows that the length of stays of females in hospitals is skewed to the right. So we say that the mean is more than the median. b) The distribution of the length of hospital stays of female heart attack patients is bimodal and skewed to the right, with a stay of 1 day to 36 days. The distribution is centered around 8 days, and the typical stay is 1-15 days. c) The median and IQR would be used to summarized the distribution of hospital stays, because the distribution is strongly skewed.
