Suppose a researcher selects a sample of 30 adult females and finds the mean of the measure of the triglyceride levels for a sample of subjects to be 187 milligrams/deciliter. The process continues for 100 samples. At that point, the mean becomes a random variable and the means of some of the different samples are 187, 192, 184, . . . 196.
What can you say about the means of the sample with respect to the population mean?
