The waiting time (in minutes) was measured for a random sample of patients with non-life threatening injuries in emergency rooms at four local hospitals who arrived between 2:00 and 3:00pm on a particular Saturday. The results of the ANOVA and the plot of the residuals follow: Using the information in the outputs, is there evidence that the distribution of observations is normal in each hospital's population?
