An annual state assessment test is a standards-based, criterion-referenced assessment used to measure a student?s attainment of the academic standards while also determining the degree to which school programs enable students to attain proficiency of the standards. For a sample of schools, three relationships are considered: percentage passing versus school mean score, percentage passing versus percentage who participated (took the test) in each school, and percentage passing versus percentage of disadvantaged students in the school. In this exercise, you are to identify which one of the three reported regression results corresponds to each of the three scatterplots. 3. 95% confidence interval for beta 1 for regression of % passing on disadvantaged (plot on the right) a. (-0.78, -0.50) b. (0.17, 0.20) c. (0.30, +1.61)

Solution

Option a for the third plot,

Option b for the second plot and

option c for the first plot
