1. In the book Design and Analysis of Experiments, 8th edition (2012, John Wiley & Sons), the results of an experiment involving a storage battery used in the launching mechanism of a shoulder-fired ground-to-air missile were presented. Three material types can be used to make the battery plates. The objective is to design a battery that is relatively unaffected by the ambient temperature. The output response from the battery is effective life in hours. Three temperature levels are selected, and a factorial experiment with four replicates is run. The data are as follows: Table 11.
(a) Test the appropriate hypotheses and draw conclusions using the analysis ether either firing temperature or furnace position affects the baked density of a carbon anode. The data are as follows: Table 12.
(a) State the hypotheses of interest.
(b) Test the hypotheses in part (a) using the analysis of variance with a = 0.05. What are your conclusions?
(c) Analyze the residuals from this experiment.
(d) Using Fisher's LSD method, investigate the differences between the mean baked anode density at the three different levels of temperature. Use a = 0.05.
