   Question

   Below is a partially completed ANOVA table.

   ——– —- —- —- — Source df SS MS F Groups 3 Error 25 20 Total 28 35 ——– —- —- —- —

   Given a significance level of 0.05. Then it follows from the table that

   
   
   1. FALSE: 4 ≤ F ≤ 5 and so the null hypothesis of ANOVA can be rejected.
   2. TRUE: 6 ≤ F ≤ 7 and so the null hypothesis of ANOVA can be rejected.
   3. FALSE: F ≤ 2 and so the null hypothesis of ANOVA cannot be rejected.
   
   
   1. 4 ≤ F ≤ 5 and thus the null hypothesis of ANOVA can be rejected…: Incorrect
   2. 6 ≤ F ≤ 7 and thus the null hypothesis of ANOVA can be rejected: Correct
   3. F ≤ 2 and so the null hypothesis of ANOVA cannot be rejected: Incorrect
