1. The prices of pigs auctioned at a fair are normally
distributed with a population mean of $990 and a
population standard deviation of $83. Random samples of size 20 are
drawn from the population.
a. Find the mean of the sampling distribution and the standard
deviation of the sampling
distribution.
b. If I were to select one sample of size 20, what is the
probability that its mean is more than
$1000? Write the probability statement.
c. Draw a graph of the sampling distribution and the probability in
part b. Be sure to label the axis
correctly.
