a) What hypotheses would you test to decide whether the mean lengths of stay are not the same for all four health plans? (Let l,, Hg, Ha, and H, be the true mean length of hospital stay for the four different health plans.) PM = Et = 2 = F :0H O H at least two of the four u's are different H all four of the u's are different O Hoi at least two of the four u's are different H : Hy = Hz = Hg = H4 H: at least two of the four u's are the same O Hot all four of the u's are different Hgi Hy = Hq = Hg " H4 b) If each sample consisted of six individuals and the value of the ANOVA F statistic was F = 3.17. What can be said about the P-value for this test? O P-value > 0.100 O 0.050 < P-value < 0.100 O 0.010 < P-value < 0.050 O 0.001 < P-value < 0.010 O P-value < 0.001 What conclusion would be appropriate for a test with a = 0.01? O Fail to reject Ho: There is not convincing evidence that the mean length of hospital stay is not the same for all four health plans. O Fail to reject Ho: There is convincing evidence that the mean length of hospital stay is not the same for all four health plans. O Reject Ho. There is convincing evidence that the mean length of hospital stay is not the same for all four health plans. O Reject Ho: There is not convincing evidence that the mean length of hospital stay is not the same for all four health plans. c) Answer the question posed in part (b) if the F value given there resulted from sample sizes n, = 7, n = 6, n3 = 6, and na = 5. What can be said about the P-value for this test?
