3.6 With the increase in the mobility of the population in the United States and with the increase in home-based employment, there is an inclination to assume that the personal income in the United States will become fairly uniform across the country. The following table provides the per capita personal income for each of the 50 states and the District of Columbia. Income (thousands of dollars) Number of States 22.0–24.9 5 25.0–27 .9 13 28.0–30.9 16 31.0–33.9 9 34.0–36.9 4 37 .0–39.9 2 40.0–42.9 2 Total 51 a. Construct a relative frequency histogram for the income data. b. Describe the shape of the histogram using the standard terminology of histograms. c. Would you describe per capita income as being fairly homogenous across the United States?
