In a certain region, the mean annual salary for HVAC contractors is $53,100. Let x be a random variable that represents a plumber's salary. Assume the standard deviation is $1745. If a random sample of 40 plumbers is selected, what is the probability that the sample mean is between $53,000 and $54,000?
