Part 1: Sampling from a normal population. Suppose we are concerned about the speeds of cars on a local highway. It is reasonable to assume that the speeds follow a normal distribution with mean 50 mph and standard deviation 16 mph. These can be simulated using the NORMINV function in Excel. We shall take 100 samples, in rows 16 to 115 of the ...

This Excel chart illustrates the concept by showing two probability density functions. The solid curve represents the distribution of the sample mean with a sample size of 50; the dotted curve is the analogous distribution when the sample size is 16. Note that the area under each curve is 1.0 and that both are centered on the true mean of 87 ...
