B) at least 5 of the comparisons of means $\bar { X } _ { i }$ versus $\bar { X }$ , would be significant using the Scheffe test.
C) all 10 of the comparisons of means $\bar { X } _ { i }$ versus $\bar { X } _ { j }$ would be significant using the Scheffe test.
D) at least 1 of the comparisons of means $\bar { X } _ { i }$ versus $\bar { X } _ { j }$ would be significant using the Scheffe test.
