2. Integrated circuits are manufactured on silicon wafers through a process that involves a series of steps. An experiment was carried out the effect on the yield of using three methods in the cleansing step. The results of the experiment can be found on the Yield-One Way.xIs Excel file. The reported values are an index of production (higher is better!). a. Set up the null and alternative hypotheses. b. Using the Excel file indicated above, is there evidence that the results of the cleaning methods are statistically different? In answering the question, interpret the p-value of this test
