Suppose that for a particular type of car, it is known that the miles per gallon obtained on the highway by individual cars is normally distributed, with a mean of 32 miles per gallon and a standard deviation of 4 miles per gallon. What is the probability that a randomly selected sample of 5 cars of this type would have an average fuel efficiency of between 30 and 35 miles per gallon on the highway? I want to know how...
