   Below is a partial ANOVA table of a oneway ANOVA on three groups with 5 observations each.

   ——————— ——- —- ——- —— Source of variation SS df MS F Between groups 40.80 2 20.40 5.81 Within groups Total 82.93 ——————— ——- —- ——- ——

   When testing, with α =5%, what is the critical value of H₀: μ_l = μ₂ = μ₃ and what is the conclusion?

   
   
   1. FALSE: Critical value = 3.74, reject H0
   2. TRUE: Critical value = 3.89, reject H0
   3. FALSE: Critical value = 3.89, do not reject H0
   4. FALSE: Critical value = 19.41, do not reject H0
   
   
   1. Critical value = 3.74, reject H0: Incorrect
   2. Critical value = 3.89, reject H0: Correct
   3. Critical value = 3.89, do not reject H0: Incorrect
   4. Critical value = 19.41, do not reject H0: Incorrect
