Because of the increased cost of housing, a national real estate board wants to compare the proportion of homeowners living in metropolitan areas with the proportion living in rural areas. The board members know that housing costs are higher in metropolitan areas, but they also know that small town and rural residents have substantially lower income levels. The board has decided to find out whether the corresponding proportions differ from one another. A random sample of 150 persons living in rural areas contains 93 homeowners, while a sample of 225 persons living in metropolitan areas has 126 homeowners.
