ANOVA Test An electronics engineer is interested in the effect of tube conductivity of three different types of coating for cathode ray tubes in a telecommunications system display device. The following conductivity data is obtained: Coating Type 1 Coating Type 2 Coating Type 3 12 14 15 10 15 16 11 13 17 12 14 16 Can we conclude that there is a difference in mean conductivity due to the type of coating? Hypothesis Statements Null Hypothesis: All population means are equal Alternate Hypothesis: Not all population means are equal Significance Level The significance level selected for this test is 5%.
