This exercise requires that you have first done Exercise 3.199. In Example 3.12 on page 109, we found that, considering the five starting players on Team II a sample of all male starting college basketball players, the mean and standard deviation of the heights are 75 inches and 6.2 inches, respectively. Explain why, numerically, the sample mean of 75 inches is the same as the population mean found in Exercise 3.199(a) but that the sample standard deviation of 6.2 inches differs from the population standard deviation found in Exercise 3.199(b). |
