The distribution of incomes is strongly skewed to the right for individuals in the U.S. The following histograms represent mean income from 200 samples randomly selected from the U.S. population. One histogram is based on samples of size of n = 4, one on samples of size of n = 40, and one on samples of size of n = 100 (not necessarily in this order.) Which histogram represents sample means for n=4? [ Select ] ["A", "B", "C"] Which histogram represents sample means for n=100? [ Select ] ["A", "B", "C"] As sample size increases, the shape of the distribution of sample means becomes more [ Select ] ["normal", "skewed to the left", "skewed to the right", "uniform"]
