STAT exam

[Nice Heart]

these are some of the questions
1 : The F statistic is
ratio of two variances

2 : when we compute ANOVA , we use
F distribution

3 : Null hypotheses for ANOVA conduct that the populations mean are
equal

4 : when we reject the Null hypotheses , that means
at least one of pair populations mean is different

This is my simple language , I hope that there is no mistakes
