Question
The dry shear strength of birch plywood bonded with different resin glues was studied with a completely randomized designed experiment. Here are the data: Glue A (102; 58; 45; 79; 68; 63; 117) Glue C (100; 102; 80; 119) Glue F (220; 243; 189; 176; 176). SSE = 8167.55; MSE = 628.27; and F stat = 37.99. Define the appropriate null and alternate hypotheses.
- A. H1: μ1 = μ2 = μ3 vs Ho: At least 2 of the means differ
- B. Ho: μ1 ≠ μ2 ≠μ3 vs H1: μ1 = μ2 = μ3
- C. H0: μ1 = μ2 = μ3 vs H1: At least 2 of the means differ
- D. Ho: At least 2 of the means differ vs H1: μ1 = μ2 = μ3
