The cathode warm-up time (in seconds) was determined for three different types of X-ray tubes using fifteen
Question:
Do an analysis of variance on these data and test the hypothesis that the three tube types require the same average warm-up time. Include a pair of orthogonal contrasts in your ANOVA table. Define one of the contrasts so it tests H0: μA = μC. What does the other contrast test? Check to see that the sums of squares associated with your two contrasts verify the statement of Theorem 12.4.1.
