A random sample of size n is to be drawn from a large population with mean 150 and standard deviation 20, and the sample mean x is to be calculated. To see the effect of different sample sizes on the standard deviation of the sampling distribution of x, plot s>2n against n for n = 1, 2, 5, 10, 25, 50, and 75.
