Question: The volume of soft drink in plastic bottles is a normal random variable with mean 16 ounces and standard deviation 0.6 ounces.

a.) If a bottle is selected at random, find the probability that it contains more than 15.8 ounces of soft drink.

b.) A random sample of 25 bottles is selected from a large quantity of filled bottles. Write down the sampling distribution of sample means. Give the mean and standard deviation of the sampling distribution, and compare the shape of the sampling distribution to the shape of the original distribution of soft drink volumes.

c.) Find the probability that the mean volume of soft drink in the 25 sampled bottle is less than 15.8 ounces.
