The Academic Performance Index (API) is a measure of school
achievement based on the results of the Stanford 9 Achievement
test. Scores range from 200 to 1,000, with 800 considered a
long-range goal for schools. The following table shows the API
(y) for eight elementary schools, along with the percent
of students (x) at each school who are considered "English
Learners" (EL).
1. Construct the ANOVA table for the linear regression. (Round
your answer to one decimal place.)
2.
Assuming that x and y are linearly related,
calculate the least-squares regression line. (Round all numerical
values to four decimal places.)
