A firm is trying to higher new management trainees. After the preliminary interview the potential trainees are ranked into four (4) groups: Poor, Fair, Good and Excellent. The firm then administers three computer-based aptitude tests to evaluate the Verbal Ability, Data Interpretation and Problem Solving of the prospective management trainee. The candidates are allowed to take each test twice and the higher grade is reported. The scores obtained are listed in the following table: Test Type Subject Type Verbal Ability 65 Data Problem Interpretation Solving 71 69 73 78 Poor Fair 75 75 70 65 78 82 76 75 68 69 72 68 78 74 79 Good Excellent 64 72 83 84 (d) Using R-Studio, derive the analysis of variance table. Ensure that you provide the code used and relevant output tables. (e) State the null hypothesis(es), the decision rule for a = 0.05 and make the decision for each hypothesis. () Using R-Studio, carry out relevant tests to determine if the assumptions of the ANOVA analysis were violated. Carefully discuss your findings quoting relevant statistics.
