he 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 n Mean Marketing 19 44.37 Management 11 43.18 Other 14 42.21 Finance 45 41.80 Accountancy 36 37.56 MIS 47 32.21 (A) Complte the following ANOVA table: Source of Variation SS 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…

Read the following on attendance and grades, and answer the questions. A study revealed that students from a certain local college in Bulacan who attended class 95 to 100% of the time usually received a grade of 1.0 in the class. Students who attended class 80 to 90% of the time usually received a 1.5 or 1.75 in the class. Students who attended class less than 80% of the time usually received a 3 or a 5 or eventually withdrew from the class. Many factors affect a student’s grade in a course. One factor that has considerable control over is attendance. One can increase the opportunities for learning by attending class more often. 1. What are the variables under study? Answer: 2.
