Data are collected on 15 individuals and two models are considered:

Model 1: model with 2 predictors (A and B), SStotal = 360, SST = 200

Model 2: model with 4 predictors (A, B, C and D), SStotal = 360, SST = 270

1. The standard error of the complete model is equal to  .

2. The number of predictors to test to evaluate whether the restricted model is sufficient is equal to

3. The partial F-test in 2. is equal to   

4. The critical value (rejection region) for the partial F-test is equal to   

5. The adjusted coefficient of determination for the complete model is equal to  %
