A town has 500 real estate agents. The mean value of the
properties sold in a year by these agents is $950,000, and the
standard deviation is $250,000.
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
$973,000?
c. What is the probability that the sample mean exceeds
$927,000?
d. What is the probability that the sample mean is between
$924,000 and $977,000?
