Employees of a state university system can choose from among four different health plans. Each plan differs somewhat from the others in terms of hospitalization coverage. Four random samples of recently hospitalized individuals were selected, each sample consisting people covered by a different health plan. The length of the hospital stay (number of days) was determined for each individual selected. USE SALT (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.) ⒸH₂² H₂ = H₂ = H₂ = H₂ H: all four of the 's are different O H₂H₂H₂H₂ = H₂ H, at least one pair of the four 's are the same OH: at least one pair of the four μ's are different H₂H₂ = H₂ = H₂ = H4 OH₂: H₂ = H₂ = H₂ = H₂ H₂: at least one pair of the four 's are different O Ho: all four of the 's are different H₂H₁ H₂ H₂ = H₂ (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 OP-value < 0.001 What conclusion would be appropriate for a test with a = 0.01? O Fail to reject H. There is not convincing evidence that the mean length of hospital stay is not the same for all four health plans. O Reject H. 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 H. There is convincing evidence that the mean length of hospital stay is not the same for all four health plans. O Reject H. There is 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 n₂ = 8, n₂ = 7, n₂ = 7, and n = 6. 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 The conclusion is the following. O Reject Ho. There is convincing evidence that the mean length of hospital stay is not the same for all four health plans. O Fail to reject H. 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 H. 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.
