Question 2. An industrial engineer wishes to test the effect of four chemical agents on the strength of a particular type of cloth. Because there might be variabity from one bolt to another, the chemist decides to use a randomized block design, with the bolts of cloth considered as blocks. She selects five bolts and applies all four chemicals in random order to each bolt. The resulting tensile strengths follow. Analyze the data from this experiment (use a = 0.05) and draw appropriate conclusions. The data are as follows: replace x with the last two digit of your student id (my id is 35026, then x is 26) Use a=0.05. bolt Chemic 1 al 1 4 14 6. 9 3 14 9 4 3 6 Solve the following questions (No software plot or solution): a) b) c) Prepare ANOVA showing all calculation is there any significant factor? Explain? Plot the residual plots vs predicted, comment on the figure Plot the residual plots vs order, comment on the figure 2. 3. LO LO
