The annual salary of teachers in a certain state has a mean of $54,000 and standard deviation of $5,000. What is the probability that a randomly selected teacher from this state has an annual salary of $55,500 or more.
Added by Elizbeth H.
Step 1
In this case, x = $55,500, μ = $54,000, and σ = $5,000. z = (55,500 - 54,000) / 5,000 z = 1,500 / 5,000 z = 0.3 Show more…

The average teacher's salary in Connecticut (ranked first among states) is $57,337. Suppose that the distribution of the salaries is normal with a standard deviation of $7500. Round intermediate z value calculations to two decimal places and the final answers to at least four decimal places. What is the probability that a randomly selected teacher makes less than $43,800 per year?
