A study is done to determine the influence of the wear, y, of a bearing as a function of the load, a;, on the bearing. A designed experiment is used for this study. Three levels of load were used, 700 lb, 1000 lb, and 1300 lb. Four specimens were used at each level and the sample means were, respectively, 210, 325, and 375.(a) Plot average of wear against load.(b) From the plot in (a), does it appear as if a relationship exists between wear and load?(c) Suppose we look at the individual wear values for each of the four specimens at each load level. Plot the wear results for all specimens against the three load values.(d) From your plot in (c), does it appear as if a clear relationship exists? If your answer is different from that in (b), explainwhy.
