question 91

Multiple Choice

A manufacturing company produces part QV2Y 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 QV2Y 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. At a significance level of .05, the management wants to perform a hypothesis test to determine whether the quality of items produced appears to be independent of the production process used. What is the rejection point condition?

• A) Reject H₀ if χ² > .10257
• B) Reject H₀ if χ² > 9.3484
• C) Reject H₀ if χ² > 5.99147
• D) Reject H₀ if χ² > 7.37776
• E) Reject H₀ if χ²> 7.81473
