Suppose that we randomly select a sample
of 80 measurements from an infinite
population having a mean equal to 30 and
a standard deviation equal to 5. What is
the mean and standard deviation of the
sampling distribution?
Omean=30, SD=0.31
Omean=30, SD=0.56
O mean=80, SD=0.31
mean=80, SD=0.56

Suppose that we randomly select a sample of 144
measurements from an infinite population having a
mean equal to 32 and a standard deviation equal to
6. What is the mean and standard deviation of the
sampling distribution?
mean = 32, SD = 0.04
mean = 32, SD = 0.50
mean = 144, SD = 0.75
mean = 144, SD = 0.50
