Hey Can you solve Q3,Q4,Q5

Q3. [5 points] In each of questions 1 and 2, the student made a decision to reject Ho vs. not reject Ho. Was the outcome of these two decisions a coincidence, or not? Why or why not? Note: A coincidence is when two things happen but are not related. Circle one: Coincidence Not a coincidence Why or why not? Q4. [Total 4 points] The student also investigated the impact of Covid19 pandemic on UIC students' academic performance by comparing their GPAs in the semester before the pandemic started and the one right after that. The test result showed that the average difference in GPA was 0.005, and the p-value for the test was 0.02. Assess the statistical and practical significance of the test result if alpha = 0.01. a. [2 points] Is it statistically significant? Circle one: Yes No Why? b. [2 points] Is it practically significant? Circle one: Yes No Why? Q5. [Total 4 points] The student also executed a regression to predict the average GPAs (the dependent variable, or Y) using the number of absences (the independent variable, or X). The students expected that as the number of absences increases the GPA decreases. a. [2 points] State Ho and Ha with regards to (31: Ho: Ha: b. [2 points] The standard deviation of Y is 19. The square root of the sum of the squared residuals divided by n-2 equals 11 (note: the formula on slide 21 of Chapter 10). Does this suggest that the regression fits the data well? (No explanation required.) Circle one: Yes No
