We know that, F statistics is the ratio of variances.
It's a ratio of explain variation to unexplain variation.
So F statistics become zero if there is no variation.
If no variation then standard error also become zero.
Hence, F statistics become zero if the standard error of the estimate zero.
So, option (B) is correct.

Which of the following statements is true with respect to a simple linear regression model? a. The regression slope coefficient is the square of the correlation coefficient b. It is possible that the correlation between a y and x variable might be statistically significant, but the regression slope coefficient could be determined to be zero since they measure different things c.

Which of the following statements about the t-statistic in regression is not true? a. The t-statistic provides some idea of how well a predictor predicts the outcome variable. b. The t-statistic is equal to the regression coefficient divided by its standard deviation. c. The t-statistic can be used to see whether a predictor variables makes a statistically significant contribution to the regression model. d. The t-statistic tests whether the regression coefficient, b, is equal to 0.
