11.5 Consider an experiment with four groups with eighth values in each. For the
following ANOVA summary table, fill in all the missing results.
Source Degree of freedom Sum of Square Mean Square(Variance) F
___________________________________________________________________________________
Among groups c1=? SSA=? MSA=80 F=?
with
groups nc=? SSW=560 MSW=?
Totals n1=? SSt=?
11.6 You are working with the same experiment as in Problem 11.5
(a). At the 0.05 level of significance, state the decision rule for testing the null
hypothesis that all four groups have equal population means.
(b). What is your statistical decision?
(c). At the 0.05 level of significance, what is the upper tail critical value from
the Students range distribution?
(d). To perform the TukeyKramer procedure, what is the critical range?

I'm stuck on this too
