2. A mechanical engineer is studying the thrust force developed by a drill press. He suspects that the drilling speed and the feed rate of the material are the most important factors. He selects four feed rates and uses a high and low drill speed chosen to represent the extreme operating conditions. He obtains the following results. (A) Feed Rate (B) in thousandths Drill Speed 15 30 45 60 125 2.72 2.55 2.65 2.83 2.78 2.53 2.67 2.76 200 2.83 2.85 2.89 2.96 2.86 2.83 2.87 2.89 a. Is there any indication that either factor affects the thrust force? Is there any interaction between the factors? Use a = 0.05. With all sets of hypotheses include in addition; test statistic value, p-value, decision and conclusion. i. State all sets of Hypotheses, ii. What is the test statistic and p-value for each hypothesis, ii. Write the decision and Conclusion. b. Write down the appropriate statistical model and its assumption to be valid. C. Analyze the residuals from this experiment. Are the basic analysis of variance assumptions satisfied? d. Use Fisher's test to compare all pair of thrust force means for all the levels of feed rate and Drill speed. If high level of thrust force is desirable, what level of feed rate and drill speed would you specify? e. Suppose that Feed rate cannot be easily controlled in the environment in which the Drill speed is to be used. Does this change your answer for part d? 2.
