Do the needs of patients in the emergency room differ for those who come by car vs. those by ambulance? Of the randomly selected emergency room patients who came by car 67 had an injury, 60 were sick, 44 had heart problems and 67 had other needs. Of the randomly selected emergency room patients who came by ambulance 42 had an injury, 25 were sick, 48 had heart problems and 31 had other heeds. Conduct the appropriate hypothesis test using an a = 0.05 level of significance.
