Suppose that you are interested in estimating the average numberof miles per gallon of gasoline your car can get. You calculate themiles per gallon for each of the next twenty-five times you fillthe tank. Suppose that in truth, the values for your car arebell-shaped, with a mean of 20 miles per gallon and a standarddeviation of 1. Find the possible sample means you are likely toget based on your sample of twenty-five observations. Consider theintervals into which 68%, 95%, and almost all of the potentialsample means will fall, using the Empirical Rule. (Round allanswers to the nearest thousandth.)
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 rangebetween ____ and ____.
