In a One-Factor Random-Effects Model, Suppose We Find That the Effect

Multiple Choice

In a one-factor random-effects model, suppose we find that the effect of factor A is significant at $\alpha$ = .05.

A) We should conduct MCP on
B) We should conduct MCP only when A has more than two levels.
C) We conclude that not all the $\mu$ _.j. are equal at significance level .05.
D) We are sure that the effect of A will also be significant if we have applied a fixed-effects model to the data.
