1. 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 by 10 workers. The number of units assembled correctly was recorded, and the ANOVA procedure was applied to the resulting data set. The following results were obtained: SST=12,800;SSE=9880. (a). What hypotheses are implied in this problem? ( 1 point) (b). Set up the ANOVA table for this problem. (Tips: the p-value must be chosen as the smallest range). (7 points) (c). At the =0.05 level of significance, can we reject H0 in part (a)? Explain (list the reasons). ( 2 points)
