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
