question 2

Essay

Your used car is expected to last an average of 200,000 miles with a standard deviation of 25,000 miles before it requires a new transmission.
A) Use Chebyshev's Theorem to approximate the probability that the engine will last between 150,000 miles and 250,000 miles.
B) Assume a symmetric bell-shaped distribution to approximate the probability that the engine will last between 150,000 miles and 250,000 miles.
