Suppose that a researcher, using data on class size (CS) and average test scores from third-grade classes, estimates the OLS regression + CS, = , SER = () () Construct a 95% confidence interval for , the regression slope coefficient. The 95% confidence interval for , the regression slope coefficient, is ( nothing, nothing). (Round your responses to two decimal places.) The t-statistic for the two-sided test of the null hypothesis : = is nothing. (Round your response to four decimal places.) Note: Assume a normal distribution. The p-value for the two-sided test of the null hypothesis : = is nothing. (Round your response to four decimal places.) Do you reject the null hypothesis at the % level? A. , because the p-value is than 0.01. B. Yes, because the t-statistic is less than 2.58. C. Yes, because the t-statistic is greater than 2.58. D. , because the p-value is than 0.01. The p-value for the two-sided test of the null hypothesis : = is nothing. (Round your response to four decimal places.) Without doing any additional calculations, determine whether is contained in the 95% confidence interval for . A. No, is not contained in the 95% confidence interval for . B. Yes, is contained in the 95% confidence interval for . The 99% confidence interval for is ( nothing, nothing). (Round your responses to one decimal place.)
