c) Is there evidence to support that the model is significant?
Test using ?=0.05α=0.05.
1. ?0:?1=...=?8H0:β1=...=β8 vs ??:Ha: At least one ?β differs from
0.
2. Test statistic: F =
3. Critical value: ??Fα =
4. Conclusion: ?0H0. (Type either Reject or Fail to
reject)
There evidence that the part of the model which concerns
the departments is significant. (Type either is or is not)
