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.
Please see the info below. Please include additional examples and strategies in solving this problem, besides what has been offered. Please include an explanation for what was done. For the following exercises, identify the type of data that would be used to describe a response (quantitative discrete, quantitative continuous, or qualitative), and give an example of the data. 58. most-watched television show is a categorical variable (categorical can be divided into groups and a variable that isn't numerical.), so it is qualitative.
