Valvoline has filling machines that are adjusted to pour 12 ounces of oil into a 12-ounce bottle. The actual amount of oil poured into each bottle isn't 12 ounces, it varies between bottles. It has been observed that the net amount of oil in each bottle has a normal distribution with a mean of 12 ounces and a standard deviation of .015 ounces. 1) What is the probability that a randomly selected bottle of Valvoline contains less than 11.97 ounces of oil? 2) What is the probability that a randomly selected bottle of Valvoline contains between 11.97 and 11.99 ounces of oil? 3) What is the probability that a randomly selected bottle of Valvoline contains more than 11.97 ounces of oil?
