True/False

In trying to obtain a model to estimate grades on a statistics test,a lecturer wanted to include,among other factors,whether the person had taken the course previously.To do this,the lecturer included a dummy variable in her regression that was equal to 1 if the person had previously taken the course,and 0 otherwise.The interpretation of the coefficient associated with this dummy variable would be the mean amount the repeat students tended to be above or below non-repeaters,with all other factors the same.
