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 ten times you fill the tank.
Suppose that in truth, the values for your car are bell-shaped,
with a mean of 25 miles per gallon and a standard deviation of 1.
Find the possible sample means you are likely to get based on your
sample of ten observations. Consider...
