A Manufacturing Company Produces Part A732 for the Aerospace Industry

question 19

Multiple Choice

A manufacturing company produces part A732 for the aerospace industry.This particular part can be manufactured using 3 different production processes.The management wants to know if the quality of the units of part A732 is the same for all three processes.The production supervisor obtained the following data: Process 1 had 29 defective units in 240 items,Process 2 produced 12 defective units in 180 items,and Process 3 manufactured 9 defective units in 150 items. Chi-Square Contingency Table Test for Independence At a significance level of .10,the management wants to perform a hypothesis test to determine if the quality of the items produced appears to be independent of the production process used.Based on the results summarized in the MegaStat/Excel output provided in the table above,we:

• A)Reject H₀ and conclude that the quality of the product is not the same for all processes.
• B)Reject H₀ and conclude that the quality of the product is dependent on the manufacturing process.
• C)Do not reject H₀,and conclude that the quality of the product does not significantly differ among the three processes.
• D)Reject H₀ and conclude that the quality of the product is independent of the production process utilized.
• E)Both reject H₀ and conclude that the quality of the product is not the same for all processes and reject H₀ and conclude that the quality of the product is dependent on the manufacturing process are correct.
