(a) What hypotheses would you test to decide whether the mean lengths of stay are not the same for all four health plans? (Let H₁ H₂ H3, and 4 be the true mean length of hospital stay for the four different health plans.) O Ho: H₁ H₂ H3 H4 H: all four of the μ's are different O Ho: H₁ H₂ H3 H4 H: at least one pair of the four μ's are the same. O Ho: at least one pair of the four u;'s are different H₂H₁ H₂ H3 H4 O Ho H1 H₂ H3 H4 H: at least one pair of the four 's are different O Ho: all four of the u's are different HH₁ H₂ H3 H4 (b) If each sample consisted of seven individuals and the value of the ANOVA F statistic was F= 3.37. What can be said about the P-value for this test? OP-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 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.
