If you did find a sample mean of MORE THAN $67,315 would you find that unusual? What could
you conclude?
O It is not unusual to find a sample mean more than $67,315, since the probability is at least
5%. If you find a sample mean more than $67,315, then it may indicate that the
population mean has not changed.
O It is not unusual to find a sample mean more than $67,315, since the probability is less
than 5%. If you find a sample mean more than $67,315, then it may indicate that the
population mean has not changed.
