Chapter 2, Problem 50SE
Education Level and Household Income. The U.S. Census Bureau serves as the leading source of quantitative data about the nation’s people and economy. The following crosstabulation shows the number of households (1000s) and the household income by the level of education for heads of household having received a high school degree or more education (U.S. Census Bureau website, https://www.census.gov/data/tables/time-series/demo/income-poverty/cps-hinc.html).
TABLE 2.17 Betas for Dow Jones Industrial Average Companies
- a. Construct a percent frequency distribution for the level of education variable. What percentage of heads of households have a master’s or doctoral degree?
- b. Construct a percent frequency distribution for the household income variable. What percentage of households have an income of $50,000 or more?
- c. Convert the entries in the crosstabulation into column percentages. Compare the level of education of households with a household income of under $25,000 to the level of education of households with a household income of $100,000 or more. Comment on any other items of interest when reviewing the crosstabulation showing column percentages.

She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference?
