and some also buy a doughnut. The shop owner believes that the
number of cups he sells each day is normally distributed with a
mean of 310 cups and a standard deviation of 25 cups. He also

has been $265. To determine whether the changes have signficantly
reduced costs, the university takes a sample of 50 classrooms. They
find that the average cost for 1 week is $247 with a standard
