Independent random samples of 500 households were taken from a large metropolitan area in the United States for the years 1950 and 2000. Histograms of household size (number of people in a household) for the years are shown below. Compare the distributions of household size in the metropolitan area for the years 1950 and 2000. Histogram A starts at 1 and ends at 14 on the x axis, “Household size in 1950”. At 1 the frequency is low and increases until it peaks at 4 then decreases until it reaches 14.Histogram B starts at 1 and ends at 12 on the x axis, “Household size in 2000”. At 1 the frequency is medium, at 60, and then increases to a peak at 2, dips at 3, then reaches the peak value again at 4. Then it decreases until it reaches the lowest point at 12.
