1. An electronics engineer is interested in the effect on tube conductivity of five different types of coating for cathode ray tubes in a telecommunications system display device. 4 samples for each is type of coating are take. a. Below the ANOVA table fill in the missing entries. Can you isolate any differences in mean conductivity due to the coating type? Test the hypotheses at a = 0.05. ANOVA Table Source Df 5S MS F C Type 265.1 Error ? Total 1303.8 b. Below the residuals graphs for this experiment. Use them to check the assumptions for this model.
