question 55

Multiple Choice

Assume that the conclusion from an ANOVA is that the null hypothesis is rejected; in other words, the 7 population means (from samples of the same size) are not all equal. We should expect that:

• A) all 21 of the comparisons of means \(\overline { \mathrm { X } } _ { i \text { versus } } \overline { \bar { X } } _ { j \text { would be significant using the Tukey test. } } ^ { \text {. } }\)
• B) at least 7 of the comparisons of means \(\bar { X } _ { i v e r s u s } \bar { X } _ { \text {jwould be significant using the Tukey test. } }\)
• C) at least 4 of the comparisons of means \(\bar { X } _ { \text {iversus } } \overline { \mathrm { X } } _ { \text {jwould be significant using the Tukey test. } }\)
• D) at least 1 of the comparisons of means \(\bar { X } _ { i \text { versus } } \bar { X } _ { \text {jwould be significant using the Tukey test. } } ^ { \text {. } }\)
