If = .05, determine whether difference among the treatment and block effects are significant.
4. The budgetary request from each of three long-term care facilities operated by our organization was based in part on the case complexity of residents. To assess the situation, suppose that we selected four patients in each of the three age groups from each of the facilities and obtained the number of secondary diagnoses presented by each resident. The results derived from the samples are as follows.
