In an experiment to assess the effect of the angle of pull on the force required to cause separation in electrical connectors, four different angles (factor A) were used, and each of a sample of five connectors (factor B) was pulled once at each angle. The data appears in the accompanying table. 0° 20 4° 6° Ho: B1 B₂=B3 =B4=ßs=0 Ha: no B, = 0 0 Ho: a, = az = az = a4 = 0 Minoa, = 0 ⒸH₁: α₁ = α₂ = α3 = α4 = 0 H: at least one a, # 0 Source A B Error Total 1 45.2 44.3 42.5 43.9 Does the data suggest that true average separation force is affected by the angle of pull?
