    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
