Question

Three different methods for assembling a product were proposed by an industrial engineer. To investigate the

 number of units assembled correctly with each method, 30  employees were randomly selected and randomly

 assigned to the three proposed methods in such a way that each method was used by10  workers. The number of

 units assembled correctly was recorded, and the analysis of variance procedure was applied to the resulting

 data set. The following results were obtained: ; . SST:10,700 SSTR:4500
