The figure shows population density(people per squaremile) for all states of a certain country. The states are divided into four geographicalregions: A,B, C, and D. Answer the questions below.

\fWhy is it best to compare medians and interquartile ranges for these data, rather than comparing means and standard deviations? Some of these data have vastly different centers, and the median and interquartile range provide more reliable information in these circumstances. These data are fairly symmetric and do not have outliers, and the median and interquartile range provide more reliable information in these circumstances. V Some of these data have outliers and/or are skewed, and the median and interquartile range are resistant to outliers. Some of these data have outliers and/or are skewed, and the median and interquartile range amplify the effects of outliers and skewness. List the approximate median number of people per square mile for each location; for example, the median for Region A is approximately 175. The median for Region B is D. The median for Region C is D. The median for Region D is D
