The life spans of a species of fruit fly have a bell-shaped distribution, with a mean of 31 days and a standard deviation of 4 days. (a) The life spans of three randomly selected fruit flies are 32 days, 27 days, and 40 days. Find the z-score that corresponds to each life span. Determine whether any of these life spans are unusual. (b) The life spans of three randomly selected fruit flies are 35 days, 23 days, and 27 days. Using the Empirical Rule, find the percentile that corresponds to each life span.

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
