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 of people covered by a different health plan. The length of the hospital stay (number of days) was determined for each individual selected. LAUSE 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 OM₂₁ ₂₂ ₂ H, at least one pair of the four 's are different OM all four of the 's are different OH at least one pair of the four 's are different H, at least one pair of the four 's are the same OM₂H₁ H₂H₂₂ Hi all four of the 's are different (b) of each sample consisted of seven individuals and the value of the ANOVA Fstatistic was F-4.17.
