The life of CD players is normally distributed with a mean of 4.4 years and a standard deviation of 1 year. We are interested in the length of time a CD player lasts. (a) (4 points) What is the distribution? X ∼ ( , ) (b) A CD player is guaranteed for three years. • (5 points) Find the probability that a CD player will break down during the guarantee period. • (5 points) Sketch the distribution. Label and scale the horizontal axis. Shade the region corresponding to the probability of breaking down in the first three years.
