An analyst has used a sample of 100 observations to create a regression equation with one independent variable. The intercept coefficient is 2.1 with a standard error of 0.4. and the slope coefficient for the variance of the prediction error is 9. If the value of the independent variable is 5.0, the prediction interval for the dependent variable at a 95% confidence level is closest to? Is it? A. 1.1 to 37.1 B. 13.1 to 25.1 C. 14.2 to 24.0
