Assume that the sample is taken from a large population and the correction factor can be ignored.
The average teacher's salary is $43152. Suppose that the distribution is normal with standard deviation equal to $7000. If we sample 100 teachers' salaries, what is the probability that the sample mean is less than $42249?
