Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes,
estimates the OLS regression
TestScore = 499.5840 + (-5.5872) × CS, R² = 0.09, SER = 11.0
(19.5840)
(2.1879)
Construct a 95% confidence interval for B₁, the regression slope coefficient.
The 95% confidence interval for B₁, the regression slope coefficient, is ( -9.93, -1.25). (Round your
responses to two decimal places.)
