The missing information in the ANOVA output is the degrees of freedom (df) for between-groups and within-groups, as well as the p-value. However, based on the given information that the calculated test statistic (F) is 8.33, we can conclude that the null hypothesis (that the means of the four majors are equal) is rejected at the 0.05 significance level. Therefore, we can answer that the statement "the mean starting salaries for graduates of engineering, business, healthcare, and computer information systems majors differ" is supported by the data.
