Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression TestScore = 562.0320 + (-6.2856) × CS, R² = 0.10, SER = 12.4 (22.0320) (2.3205) Construct a 95% confidence interval for B₁, the regression slope coefficient. The 95% confidence interval for B₁, the regression slope coefficient, is The t-statistic for the two-sided test of the null hypothesis Ho: ₁ = 0 is Note: Assume a normal distribution. The p-value for the two-sided test of the null hypothesis H₂: ß₁ = 0 is Do you reject the null hypothesis at the 1% level? A. Yes, because the t-statistic is less than 2.58. B. Yes, because the t-statistic is greater than 2.58. C. Yes, because the p-value is less than 0.01. D. No, because the p-value is greater than 0.01. (Round your responses to two decimal places.) (Round your response to four decimal places.) (Round your response to four decimal places.)
The p-value for the two-sided test of the null hypothesis Ho: ß₁ = -6.0 is (Round your response to four decimal places.) Without doing any additional calculations, determine whether - 6.0 is contained in the 95% confidence interval for ß₁. A. No, 6.0 is not contained in the 95% confidence interval for ³₁. B. Yes, -6.0 is contained in the 95% confidence interval for $₁. The 99% confidence interval for Bo is ). (Round your responses to one decimal place.)
