A soft drink vending machine is supposed to fill cups with pop. The cups hold exactly 8 oz of liquid. Suppose the actual amount dispensed by the machine follows a normal distribution with mean 7 oz. If it is found that exactly 4 percent of the cups overflow, what is the standard deviation of the normal distribution??

omg, please help.

a.) Dispense from 7.4 oz. to 7.7 oz.

b.) Dispense less than 7.0 oz.
