- Which statement is correct?
In the situation of an ANOVA with k groups of k observation each, assume that the null hypothesis was rejected on the 1%-level. Comment on the following statements.
- (a) The rejection boundary is derived from the F(k − 1, (k − 1)k)-distribution
- (b) The test statistic f exceeded the 1%-Quantile of the associated F-distribution
- (c) The test statistic f exceeded the 99%-Quantile of the associated F-distribution
- (d) The null hypothesis is also rejected on the 5% level
- (e) With probability less than 5% we obtain a value of the associated F-statistic that is greater than the observed f, if the null hypothesis is true.
- (f) If the null hypothesis was not true, we would have neither made the α- nor the β-error
- (g) We can not conclude that at least two expectations µi and µj are unequal) Distribution of the-value in simulations
