Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method, 36 employees were randomly selected and randomly assigned to the three propose by 12 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 = 12,120; SSTR = 4,540. (a) Set up the ANOVA table for this problem. (Round your values for MSE and Fto two decimal places, and your p-value to four decimal places.) Source of Variation Sum of Squares Degrees of Freedom Mean Square p-value Treatments 4540 2270 9.88 Error 7580 33 229.70 Total 12120 35 (b) Use a- 0.0s to test for any significant difference in the means for the three assembly methods. State the null and alternative hypotheses. Ho: Not all the population means are equal. Họ: At least two of the population means are equal. Hạ: At least two of the population means are different. Họ: "1" 2- 3 Hại Not all the population means are equal. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.)
