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).
