Using historical records, a manufacturing firm has developed the following probability distribution for the number of days required to get components from its suppliers. The distribution is shown here, where the random variable x is the number of days. Complete parts a through c below. a. What is the average lead time for the component? The average lead time is days. (Type an integer or a decimal. Do not round.) b. What is the coefficient of variation for delivery lead time? The coefficient of variation is %. (Round to two decimal places as needed. Do not round.)
