2. Four different designs for a digital computer circuit are being studied in order to compare the amount of noise present. The following data have been obtained Circuit Noise Observed 16 61 26 56 19 73 25 17 18 18 50 40 107 47 45 35 68 a. Is the amount of noise present the same for all four designs? Use -0.05 i. State the hypotheses, ii. What is the decision? iii. Make conclusions. b. Analyze the residuals from this experiment. Are the basic analysis of variance assumptions satisfied? i. ii. iii. State the hypotheses, What are the decisions? Make conclusions. c. Conduct another analysis with a transformation of the observed noise data and draw the appropriate conclusions. Based your answer on part (b) and the residual versus fit plot. d. Use Kruskal Wallis test to analyze the observed noise and draw conclusions. i. State the hypotheses, ii. What is the value of the test statistic? ii What is the p-value? iv. What is the decision? v. Make conclusions. 2.
