Question: Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression TestScore = 483.9720

Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression TestScore = 483.9720 + (-5.4126) x CS, R- = 0.09, SER = 10.7 (18.9720) (2.0774) Construct a 95% confidence interval for By , the regression slope coefficient. The 95% confidence interval for B, , the regression slope coefficient, is ( - 9.48 , - 1.34 ). (Round your responses to two decimal places.) The t-statistic for the two-sided test of the null hypothesis Ho: B1 = 0 is . (Round your response to four decimal places.)
