The average teachers' salary in a certain state is $57,337. Suppose that the distribution of salaries is normal with a standard deviation of $7500. Assume that the sample is taken from a large population and the correction factor can be ignored. Use a TI-83 Plus/TI-84 Plus calculator and round the answer to at least four decimal places. If we sample 55 teachers' salaries, what is the probability that the sample mean is less than $55,700?

A study was conducted to determine if the salaries of elementary school teachers from two neighboring states were equal. A sample of 100 teachers from each state was randomly selected. The mean from the first state was $29,200 with a population standard deviation of $2300. The mean from the second state was $30,600 with a population standard deviation of $2100. Test the claim that the salaries from both states are equal. Use α = 0.05.
