According to the national survey conducted by DOH on 2016, patients in the urban community, would wait an average of 6 hours to be examined in the Outpatient Department (OPD) of a public hospital. A researcher would like to determine if the average waiting time among OPD patients in rural hospitals is the same. The 15 randomly selected patients who went to the OPD of a rural hospital waited for an average of 5 hours to be assessed. The standard deviation for these 15 patients was 2.3 hours. Test the hypothesis at 0.01 alpha level. Using the 7 steps of hypothesis determine the most appropriate conclusion for the problem.
