A group of paramedics does not believe that the mean numbers of calls received in one shift are the same for the morning, afternoon, and night shifts. To test this claim, they record the number of calls received during each shift for eight days. Based on this evidence, can the paramedics conclude that the mean numbers of calls are different for the three shifts? Use α= 0.05 level of significance and assume the population distributions are approximately normal with equal population variances.
