Problem A "he breaking strengths of cables produced by a manufacturer have mean 1800 lb and a standard deviation 10olb. By a few techniques in the manufacturing process, it is claimed that the breaking strength can be increased. To test the claim, a sample of 50 cables is tested, and it is found that the mean breaking strength is 1850lb. 3. Which of the following is the most appropriate decision rule based on Problem A? A. If the z-score observed is greater than 2.33, the results are significant at o.o1 level and the null is not rejected B. If the z -score observed is lesser than 2.33, the results are significant at o.01 level and the null is rejected C. If the z -score observed is greater than or equal to 2.33, the results are significant at o.o1 level and the null is rejected D. If the z -score observed is greater than 2.33, the results are significant at o.01 level and the null is rejected Which of the following statements can describe the relationship of the computed value of statistic and the tabulated value based on Problem A? A. The value of the tabulated is twice than the value of the computed B. The value of the computed is twice than the value of the tabulated C. The value of the tabulated is greater than the value of the computed D. The value of the computed is greater than the value of the tabulated What can be concluded based on the results? A. The results are significant at o0.01 level of significance B. The results are highly significant at o.01 level of significance C. The results are not significant at the specified level of significance D. The results are not highly significant at the specified level of significance
