Extracted text: Pregunta 6 The Computer Anxiety Rating Scale (CARS) measures an individual's level of computer anxiety, on a scale from 20 (no anxiety) to 100 (highest level of anxiety). Researchers at Miami University administered CARS to 172 business students. One of the objectives of the study was to determine whether there are differences in the amount of computer anxiety experienced by students with different majors. They found the following: Major Mean Marketing Management 11 Other Finance Accountancy 36 MIS 44,37 43.18 42.21 19 14 45 41.80 37,56 47 32.21 (A) Complte the following ANOVA table: Source of Variation s df MS F-ratio F-crit Between groups 3172 5 634.4 4.9567 2.2685 Within groups 21246 166 127.988 Total 24418 171 (A) At the 0.05 level of significance, is there evidence of a difference in the mean computer anxiety experienced by different majors? Answer: Since F-ratio is greater than 2.2685, we reject the null hypothesis. Hence we conclude that there is significant difference in the mean computer anxiety (B) The results in (A) indicate that it is appropriate, use the Tukey-Kramer procedure to determine which majors differ in mean computer anxiety. Complete the table. Use q = 3.86 for all your calculations. Colum 2 is the absolute value if the difference, column 3 is the critical range, column 4 is the answer if there is significant or not. Marketing vs Management 1.19 11.70 No Marketing vs Other 2.16 10.88 No Marketing vs Finance 2.57 8.44 No Marketing vs Accountancy 6.81 8.76 No Marketing vs MIS 12.16 8.39 Yes Management vs Other 0.97 Management vs Finance 1.38 Management vs Accountancy 5.62 Management vs MIS 10.97 Other vs Finance 0.41 Other vs Accountancy 4.65 Other vs MIS 10.0 Finance vs Accountancy 4.24 6.90 No Finance vs MIS 9.59 6.44 Accountancy vs MIS 5.35 6.84 No The major(s) that differ in n mean computer anxiety : I, I,
