3. Analysis of variance (ANOVA) The following data shows the number of claims processed daily by a group of four employees of an insurance company observed during a certain number of days. Test the hypothesis that there is a significant difference in average claims per day for employees. Use a level of significance of .05. Employee 1 15 17 14 12 Employee 2 12 10 13 17 Employee 3 11 14 13 15 12 Employee 4 13 12 12 14 10 9
