A manufacturing company produces part 2205 for the aerospace industry. This particular part canbe manufactured using 3 different production processes. The management wants to know if thequality of the units of part 2205 is the same for all three processes. The production supervisorobtained the following data: Process 1 had 29 defective units in 240 items; Process 2 produced12 defective units in 180 items, and Process 3 manufactured 9 defective units in 150 items. At asignificance level of .05, the management wants to perform a hypothesis test to determine whetherthe quality of items produced appears to be independent of the production process used. 2.1 Written part 1. Produce the contingency table.2. Formulate the Hypotheses.3. What is the rejection point condition? why? Explain. (e) Reject H0 if X2 > .10257(b) Reject H0 if X2 > 9.3484(c) Reject H0 if x2 > 5.99147((1) Reject H0 if X2 > 7.37776(e) Reject H0 if x2 > 7.81473
