answer this

Survey test on mathematical skills and their disposition to the subject were administered to students. Both test use a 10-point Likert scale with 10 indicating the highest scores for each test. Scores for the students on the tests follow: Student Code Mathematical Skills Disposition A 9.5 9.3 B 9.3 9.0 C 6.4 7.1 D 4.3 3.5 5.6 6.0 8.3 7.8 7.8 8.8 H 6.8 7.0 - 5.6 6.5 7.1 8.2 1 Determine if there is a significant relationship at 5% alpha error between the two variables. 2. By what percent can the error be reduced when using the mathematical skills to explain their disposition towards the subject? 3. What model best describes the relationship of the variables? 4. Predict the disposition of a student whose mathematical skills is 2.5. SOLUTIONS
