question 36

Multiple Choice

Assume that the conclusion from an ANOVA is that the null hypothesis is rejected, in other words that the 5 population means are not all equal. We should expect that

• A) at least 3 of the comparisons of means \(\bar { X } _ { i }\) versus \(\bar { X } _ { j }\) would be significant using the Scheffe test.
• 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.
