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 = 489.1760

Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression TestScore = 489.1760 + (-5.4708) x CS, R- = 0.09, SER = 10.8 (19.1760) (2.2984) Construct a 95% confidence interval for B, , the regression slope coefficient. The 95% confidence interval for B,, the regression slope coefficient, is ( - 9.98 , -0.97 ). (Round your responses to two decimal places.) The t-statistic for the two-sided test of the null hypothesis Ho: B1 = 0 is - 2.3803 . (Round your response to four decimal places.) Note: Assume a normal distribution. The p-value for the two-sided test of the null hypothesis Ho: B, = 0 is . (Round your response to four decimal places.)
