A Manufacturing Company Produces Part 2205 for the Aerospace Industry

question 4

Multiple Choice

A manufacturing company produces part 2205 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 2205 is the same for all three processes.The production supervisor obtained the following data: The 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. At a significance level of .05,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 Mega-Stat/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)Failed to reject H₀ and conclude that the quality of the product does not significantly differ among the three processes.
• D)Failed to reject H₀ and conclude that the quality of the product is not the same for all processes.
• E)Reject H₀ and conclude that the quality of the product is independent of the manufacturing process used.
