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 $63,500. A random sample of 31 specialists is drawn from this population. What is the probability that the mean salary of the sample is less than $61,000? Assume o = $6,500. The probability that the mean salary of the sample (Round less than $61,000 is four decimal places as needed.) Interpret the results. Choose the correct answer below. O A. Only 1.61% of samples of 31 specialists will have a mean salary less than $61,000. This is an unusual event. O B. Only 16.1% of samples of 31 specialists will have a mean salary less than $61,000. This is an unusual event. OC. About 1.61% of samples of 31 specialists will have a mean salary less than $61,000. This is not an unusual event. O D.
