Wendy's fast-food restaurant sells hamburgers and chicken sandwiches. Suppose that on a typical weekday, the demand for hamburgers is normally distributed with a mean of 430 and standard deviation of 70 and the demand for chicken sandwiches is normally distributed with a mean of 150 and standard deviation of 30 . Use this information to answer the following questions. a) How many chicken sandwiches must the restaurant stock to be \( 99 \% \) sure of not running out on a given day? b) If the restaurant stocks 530 hamburgers for a given day, what is the probability that it will run out of hamburgers that day?
