Astudy was recently conducted to see whether the mean starting salaries for graduates of engineering, business, healthcare, and computer information systems majors differ. a random sample of 8 graduates was selected from each major. the following chart shows some of the results of the anova computations; however, some of the output is missing. given what is available, the proper conclusion to reach based on the sample data is that the population means could be equal using a 0.05 level of significance.
