A researcher wants to examine the production capability of three manufacturing plants that utilize different production methods of the same part in order to select a plant as a supplier for a company. The effectiveness of each plant will be measured in the number of parts it can produce in an hour. Representative hourly production amounts are recorded from each plant over a period of 12 hours and provided to the researcher. (20 points each step)

The results of each of the three plants are as follows:

Plant A	Plant B	Plant C
141	158	131
165	185	141
174	190	165
185	206	188
164	177	175
188	197	173
145	196	188
177	193	186
162	174	145
148	152	132
147	217	128
133	138	123

Use the five-step hypothesis testing process and StatCrunch to evaluate this scenario. Complete analysis and interpretation of the results. If appropriate, use diagrams or graphs. Ensure your answer is detailed in all aspects. Be sure to comment on the assumptions of the ANOVA and if there are any violations. Which manufacturing plant, or plants, if any, would you recommend as the supplier? Why? (Be sure to discuss the Tukey results).
