(a) Suppose the three real estate appraisers independently examined each of five properties chosen at random from a particular neighborhood and gave appraised values. The manager of the appraisal service that employs them suspects that systematic differences among their methods of appraisal are causing undesirable inconsistencies in appraised values provided by her service. The issue is whether there are, in fact, systematic differences among the values reported by the three appraisers. The data, APPRAISED VALUES (In thousands of dollars), are shown below. Question: What kind of statistical analysis should you perform? Choose from: (Two sample t- test, pairwise t-test, One-way ANOVA, One-way ANOVA with block, Two-way ANOVA, Factorial design). If your answer is One-way ANOVA with block, which variable does play a role of block?

Each wine was blinded and given to each judge in randomized order. The wines were scored on a 40-point scale, with higher scores meaning better wine. Based on those scores, we want to test whether there is a difference between the 4 Chardonnay wines in mean scores. Question: What kind of statistical analysis should you perform?
