Question: Baltimore Trucking Company determined that, on an annual basis, the distance traveled per truck is normally distributed with a mean of 50 thousand miles and a population standard deviation of 15 thousand miles. If a sample of 25 trucks is selected,
- What is the probability that the average distance traveled is less than 48 thousand miles?
- What is the probability that the average distance traveled is more than 52 thousand miles?
-
What is the probability that the average distance traveled is between 48 thousand miles and 52 thousand
miles? - Do we need the Central Limit Theorem to solve (a) and (b)? Why or why not? Explain.
