Suppоse yоu аre interested in estimаting the аverage number оf miles per gallon of gasoline your car can get. You calculate the miles per gallon for each of the next 25 times you fill the tank. Suppose, in truth, the values for your car are bell-shaped, with a mean of 23 miles per gallon and a standard deviation of 1. Think about the possible sample means you are likely to get based on your sample of 25 observations. Select the set of intervals into which 68%, 95%, and almost all of the potential sample means will fall. Hint: Think about the rule of sample means and then use the empirical rule.
