The amount of toothpaste in a tube is normally distributed with a mean of 6.5 ounces and a standard
deviation of 0.8 ounces. The cost of producing each tube is 50 cents. If in a quality control examination a
tube is found to weigh less than 6 ounces, it is to be refilled to the mean value at a cost of 20 cents per tube.
On the other hand, if the tube weighs more than 7 ounces, the company loses a profit of 5 cents per tube.
Assume 1,000 tubes are examined.
a). How many tubes will be found to contain less than 6 ounces? In that case, what will be the total cost of the
refill?
b) How many tubes will be found to contain more than 7 ounces? In that case, what will be the amount of
profit lost?
