In Exercise 7, you examined U.S. household size in 2010. Using these data, construct a histogram to represent the distribution of household size.
a. From the appearance of the histogram, would you say the distribution is positively or negatively skewed? Why?
b. Now calculate the median for the distribution and compare this value with the value of the mean from Exercise 7. Do these numbers provide further evidence to support your decision about how the distribution is skewed? Why do you think the distribution of household size is asymmetrical?
