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. Assume that each sample is drawn from a normal population, that the samples are independent of each other, and that the populations have the same variances.

(claim) Ha: At least one mean is differ + DOC ON (b) Identify the degrees of freedom for the numerator and for the denominator, determine the critical value, and determine the rejection region. The degrees of freedom for the numerator, d.f.N, is 3, and the degrees of freedom for the denominator, d.f.p, is 17. The critical value is Fo = (Round to two decimal places as needed.) Print Done
