Due to random variations in the operation of an automatic coffee machine, not every cup is filled with the same amount of coffee. Assume that the mean amount of coffee dispensed is 8 ounces and the standard deviation is 0.5 ounce. Use the 68-95-99.7 rule to complete the following. a. What percent of the cups should have less than 8 ounces of coffee? b. What percent of the cups should have less than 6.5 ounces of coffee?
