The article Load-Carrying Capacity of Lengthwise Cracked Wood Beams Retrofitted by Self-Tapping Screws (J. Struct. Engr. 2017)

Question:

The article “Load-Carrying Capacity of Lengthwise Cracked Wood Beams Retrofitted by Self-Tapping Screws” (J. Struct. Engr. 2017) provides data on the maximum load (kN) of J = 5 specimens of I = 4 types of wood beams used in housing: intact beams (L1), long, centered cracks (L2), short, centered cracks (L3), and long, offcenter cracks (L4).

Use a significance level of .05 to test the null hypothesis of no difference in true average maximum load for these four beam types.
