The average teacher's salary in Connecticut (ranked first among states) is $57,337. Suppose that the distribution of salaries is normal with a standard deviation of $7500. What is the probability that a randomly selected teacher makes less than $52,000 per year? What is the probability that the next teacher's salary is less than $56,000?
