Suppose that you sample 64 high school baseball pitchers in one county and find that they have a mean fastball pitching speed of 85.00 miles per hour (mph) with a standard deviation of 5.98 mph. Find a 99% confidence interval for the mean fastball pitching speed of all high school baseball pitchers in the county. Interpret the interval. Assume that the fastball ball pitching speeds are normally distributed.
