(b) showed that out of the 125 drive-through orders 50 were Beef Burger. Of the 75 orders received at the counter, 24 of these were Beef Burger. Calculate and interpret a 95% Confidence Interval for p1 ≠ p2, where p1 is the proportion of Beef Burger orders of all drive-through orders, and p2 is the proportion of Beef Burger orders of all counter orders. Does this indicate that there is a significant dierence between the two proportions? Give a reason for your answer.
