The Exponential Distribution · Exercise 31
The cost of all maintenance for a car during its first year is approximately exponentially distributed with a mean of $150.
(a) Define the random variable. X = _________________________________.
(b) X ~ = ________
(c) μ = ________
(d) σ = ________
(e) Draw a graph of the probability distribution. Label the axes.
(f) Find the probability that a car required over $300 for maintenance during its first year.
