Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression TestScore = 494.3800 + (-5.5290) x CS, R- = 0.06, SER = 10.9 (19.3800) (2.0774) Construct a 95% confidence interval for B, , the regression slope coefficient. The 95% confidence interval for By , the regression slope coefficient, is ( ). (Round your responses to two decimal places.)
