Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression TestScore= 530.8080+ (-5.9364)× CS, R² = 0.06, SER = 11.7 (20.8080) (2.3426) Construct a 95% confidence interval for B₁, the regression slope coefficient. The 95% confidence interval for B₁, the regression slope coefficient, is (-10.58,-1.29 ). (Round your responses to two decimal places.) The t-statistic for the two-sided test of the null hypothesis Ho: B₁ = 0 is -2.5341. (Round your response to four decimal places.) Note: Assume a normal distribution. The p-value for the two-sided test of the pull hypothesis H.: B. =0 is 0.0112 (Round your response to four decimal places!
