IIT JAM 2023 Question 49: Linear regression and OLS

Let y^=5.5+3.2x\hat y=5.5+3.2xy^​=5.5+3.2x be estimated on a large sample. The 95% confidence interval of the coefficient of xxx is [0.26,6.14][0.26, 6.14][0.26,6.14] and R2=0.26R^2=0.26R2=0.26. The standard error of the estimated coefficient is ________ (round off to 1 decimal place).

Plain-text version

Let ŷ=5.5+3.2x be estimated on a large sample. The 95% confidence interval of the coefficient of x is [0.26, 6.14] and R²=0.26. The standard error of the estimated coefficient is (round off to 1 decimal place).

Also written as: Let y_hat=5.5+3.2x be estimated on a large sample. The 95% confidence interval of the coefficient of x is [0.26, 6.14] and R^2=0.26. The standard error of the estimated coefficient is (round off to 1 decimal place).
