Use the technology of your choice to perform a residual analysis on the data. Salary Offers. The College Placement Council conducts surveys on salary offers to candidates for degrees and publishes its findings in A Study of Beginning Offers. To study the effects of major and degree for physics and computer-science (CS) majors receiving a bachelor’s degree, a master’s degree, or a Ph.D., independent random samples of seven candidates each were obtained from the six groups under consideration. The salary data, in thousands of dollars, are given in the following table. We performed a two-way ANOVA on the data.
