Suppose that a researcher, using data on class size (CS) and average test scores from 91 third-grade classes, estimates the OLS regression TestScore = 525.604 +(- 5.8782) x CS, R? = 0.07, SER =11.6. A classroom has 24 students. The regression's prediction for that classroom's average test score is (Round your response to two decimal places.) Last year a classroom had 21 students, and this year it has 25 students. The regression's prediction for the change in the classroom average test score is (Round your response to two decimal places.) The sample average class size across the 91 classrooms is 21.61. The sample average of the test scores across the 91 classrooms is|. (Hint: Review the formulas for the OLS estimators.) (Round your response to two decimal places.) The sample standard deviation of test scores across the 91 classrooms is (Hint: Review the formulas for the R and SER.) (Round your response to one decimal place.)
