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.)

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
