Use the following information to answer questions 1, 2, and 3.

1. Suppose that x has a normal distribution with a mean of 20 and a standard deviation of 3.  Random samples of size 36 are drawn. What is the probability that the next time x is measured that it will have a value less than 16?

2.What is the probability that the next sample taken will have an average valuegreater than 20.5?

3.What is the probability that the next sample taken will have an average value less than 17?
