A ERAU researcher wants to examine the production capability of three manufacturing plants that utilize different production
Question:
A ERAU 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 and random hourly production amounts are recorded from each plant over 12 hours and are provided to the researcher.
The results of the three plants are as follows in parts per hour:
Plant A | Plant B | Plant C |
131 | 141 | 170 |
111 | 165 | 185 |
165 | 174 | 190 |
188 | 185 | 206 |
175 | 172 | 175 |
173 | 188 | 197 |
188 | 145 | 186 |
186 | 177 | 221 |
145 | 162 | 214 |
132 | 151 | 211 |
128 | 147 | 214 |
123 | 133 | 208 |
Use StatCrunch to evaluate this scenario. Perform a complete analysis and interpretation of the results. Ensure your answer is detailed in all aspects. Be sure to comment on the assumptions of the ANOVA and if there are any violations (If there are any violations, proceed with the analysis anyway). Which manufacturing plant or plants are different from a population standpoint, if any? Which manufacturing plant, if any, would you recommend as the supplier? Why? Write up your results in APA format. Embed all StatCrunch menus and results.
