Solve using JMP software and answer step by step.
Given a recent outbreak of illness caused by E.coli bacteria, the mayor of a large city is concerned that some of his restaurant inspectors are not consistent with their evaluations of a restaurant cleanliness. In order to investigate this possibility, the mayor has five restaurant inspectors grade (scale of 0 to 100) the cleanliness of three restaurants.
Inspector | Restaurant | ||
1 | 2 | 3 | |
1 | 72 | 54 | 84 |
2 | 68 | 55 | 85 |
3 | 73 | 59 | 80 |
4 | 69 | 60 | 82 |
5 | 75 | 56 | 84 |
1.Perform some descriptive statistics on the data. What are the average cleanliness scores for the 3 restaurants and the average cleanliness score given by the 5 inspectors?
2.State the model and all of the appropriate hypotheses being tested for this Two-way ANOVA problem. (AKA list out each hypothesis you plan to test).
3.Run a two-way ANOVA analysis and draw your conclusions. What is your conclusion about the average cleanliness score between the three restaurants?
4.What is your conclusion about the effect of the 5 inspectors on the cleanliness score?
