A researcher has used a one-way analysis of variance model to test whether the average starting salaries differ among the recent graduates from nursing, engineering, business and education disciplines. She has randomly selected four graduates from each of the four areas. If MSE = 4, and SSTO = 120 complete the following ANOVA table. Is there a significant difference in the starting salaries among the four disciplines? A. Reject H0 B. Fail to Reject H0 100. Suppose you are a researcher investigating the annual sales differences among five categories of businesses. Looking at a total of 55 companies equally divided among categories groups A, B, C, D, and E.
