QUESTION6 An experiment was conducted on a large storage battery used in military equipment. The object of the experiment was to determine the effect of temperature and type of battery plate material on the effective lifetime of the battery as measured in hours. Three types of battery plate material (labeled A, B, and C) and three temperature levels (Low, Medium, and High) were studied. There were 4 batteries tested in each cell of the experiment. The following tables and graph come from the analysis of the observed data (some entries have been replaced with): Analysis of Variance Source DF Model Error Sum of Squares Mean Square F Ratio 7427.03 10.9995 675.21 P-value 53.Explanation / Answer
