A researcher investigated the number of days patients spend at a hospital. Patients were randomly selected from four regions and the number of days each patient spent at a hospital was recorded. The accompanying table shows the results. At a= 0.10, can the researcher reject the claim that the mean number of days patients spend in the hospital is the same for all four regions? Perform a one-way ANOVA test by completing parts a through d.
