Question details

Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression Testscore-515.1960-5.76 18CS, R2-.08, SER= 11.4 (20.1960)2.3426) (a) Construct a 95% confidence interval for A , the regression slope coefficient Lower bound: places.) Upper bound: places.) (b) The t-statistic for the two-sided test of the null hypothesis Ho B1 0 is Round your responses to two decimal Round your responses to two decimal (Round your response to two decimal places.) (c) The p-value for the two-sided test of the null hypothesis Ho : A (Round your response to three decimal places.) 0 is Do you reject the null hypothesis at the 1% level(yes/no)? The p-value for the two-sided test of the null hypothesis Ho :Bi- -5.5 is (Round your response to three decimal places.) without doing any additional calculations, is-5.5 is contained in the 95% confidence interval for β1 (yes/no)?(d) Construct a 99% confidence interval for βο . (Round your responses to one decimal Lower bound: place.) Upper bound place.) Round your responses to one decimal
