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.) The t-statistic for the two-sided test of the null hypothesis Ho: B₁ = 0 is - 2.5541. (Round your response to four decimal places.) 1 Suppose that (Y;, X;) satisfy the assumptions specified here and in addition, u; is N (0, 2) and independent of X;. A random sample of n = 13 is drawn and yields ŷ = 5 = 53.37 + 68.18X, R2 = 0.91, SER = 1.7 (5.7) (8.3) Where the numbers in parentheses are the homoskedastic-only standard errors for the regression coefficients Bo and ₁ respectively. Refer to the student t distribution with n − 2 degrees of freedom to answer the following questions. Construct a 95% confidence interval for B using the student t distribution (with n − 2 degrees of freedom) table available here. The 95% confidence interval for bo is [40.63, 66.11].
