You can put this solution on YOUR website! Find the probability and interpret the results. If convenient, use technology to find the probability.
The population mean annual salary for environmental compliance specialists is about $62,000.
A random sample of 34 specialists is drawn from this population.
What is the probability that the mean salary of the sample is less than $59,500?
Assume sigma equals $6,200.
z(59,500) = (59500-62000)/[6200/sqrt(34)] = -2.3512
Ans: P(x-bar < 59500) = P(z < -2.3512) = normalcdf(-100,-2.3512) = 0.0094
