11. A restaurant handles 180 customers but has 6 errors during service on Monday. The same restaurant handles 220 customers but has 8 errors during service on Tuesday. Calculate the errors per cover for each day. Assuming each error results in a guest having to wait for a dish to be remade, on which day did the restaurant staff provide higher quality service to its guests overall, as measured solely by the errors per cover rate? |
