QUESTION 3 An electronics engineer of CINCAU Son. Bhd. is interested in the effect on tube conductivity of three different types of coating for cathode ray tubes in a telecommunications system display device. Table Q3 shows the conductivity of each coating types. Use a = 0.05. At 5% of significance level, is there evidence to support the claim that the coating type affects the mean conductivity? Show the ANOVA table in your solution. Table Q3: The tube conductivity for each coating types Coating types 2 10 14 12 Tube conductivity 32 19 10 11
