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)x CS, R? = 0.09, SER=124 (22.0320) (2.2321) Construct a 95% confidence interval for p,, the regression slope coefficient. The 95% confidence interval for B,, the regression slope coefficient, is (|:|, D). (Round your responses to two decimal places.) The t-statistic for the two-sided test of the null hypothesis Hy: B, =0is D (Round your response to four decimal places.) Note: Assume a normal distribution. The p-value for the two-sided test of the null hypothesis Hy: By =0 is |:| (Round your response to four decimal places.) Do you reject the null hypothesis at the 1% level? No, because the p-value is greater than 0.01. Yes, because the p-value is less than 0.01. Yes, because the t-statistic is less than 2.58. o o wp Yes, because the t-statistic is greater than 2.58. The p-value for the two-sided test of the null hypothesis Hy: p; = -6.0is |:| (Round your response to four decimal places.) Without doing any additional calculations, determine whether - 6.0 is contained in the 95% confidence interval for ;. () A. No, -6.0is not contained in the 95% confidence interval for B (0 B. Yes, -6.0is contained in the 95% confidence interval for . The 99% confidence interval for B is (D, |:|). (Round your responses to one decimal place.)
