    ————– —- —- —- — Variation source SS df MS F Regression 54 Residual 90 9 ————– —- —- —- —

    The value of the test quantity F, the critical value and the conclusion (for testing with a risk of α = 0.05) must then be


    1. TRUE: F = 5.4, critical value = 5.12, significant
    2. FALSE: F = 2.7, critical value = 4.26, not significant
    3. FALSE: F = 5.4, critical value = 10.56, not significant
    4. FALSE: F = 0.6, critical value = 4.96, not significant

    1. F = 5.4, critical value = 5.12, significant: Correct
    2. F = 2.7, critical value = 4.26, not significant: Incorrect
    3. F = 5.4, critical value = 10.56, not significant: Incorrect
    4. F = 0.6, critical value = 4.96, not significant: Incorrect
