Suppose that you are interested in estimating the average number of miles per gallon of gasoline your car can get. You calculate the miles per gallon for each of the next twenty-one times you fill the tank. Suppose that in truth, the values for your car are bell-shaped, with a mean of 27 miles per gallon and a standard deviation of 1. Find the possible sample means you are likely to get based on your sample of twenty-one observations. What are the intervals into which 68%, 95%, and 99.7% of the potential sample means will fall, using the Empirical Rule? (Round your answers to three decimal places.)

About 68% of possible sample means will be in the range between___ and___ .

About 95% of possible sample means will be in the range between___ and___ .

About 99.7% of possible sample means will be in the range between ___and ____.
