Cups will hold 8 fluid ounces.

The amount of coffee dispensed varies according to a normal distribution

centered at the mean that is set in the machine and with standard deviation

= 0.22 ounce.

If a cup contains more than 7.4 ounces of coffee, a customer may get burned from

a spill. This could result in an expensive lawsuit for the company. On the other hand,

customers may become irritated if they get a cup with less than 6.75 ounces of coffee

from the machine. Suppose the company sets the machine's mean at = 7 ounces.
