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 $60,500. A random sample of 35 specialists is drawn from this population. What is the probability that the mean salary of the sample is less than $57,500? Assume o = $6,100. %3D The probability that the mean salary of the sample is less than $57,500 is (Round to four decimal places as needed.)
