A town has 500 real estate agents. The mean value of the properties sold in a year by these agents is $500,000, and the standard deviation is $200,000. A random sample of 100 agents is selected, and the value of the properties they sold in a year is recorded. a. What is the standard error of the sample mean? b. What is the probability that the sample mean exceeds $517,000? c. What is the probability that the sample mean exceeds $495,000? d. What is the probability that the sample mean is between $490,000 and $510,000? Click on the icon to view the standard normal table. a. The standard error of the sample mean is (Round to the nearest integer as needed.) b. The probability that the sample mean exceeds $517,000 is (Round to four decimal places as needed.) c. The probability that the sample mean exceeds $495,000 is (Round to four decimal places as needed.) d. The probability that the sample mean is between $490,000 and $510,000 is (Round to four decimal places as needed.)
