Since we are attempting to examine the behavior of a class of students, the behavior of an individual (as we calculated in objective 1) is really of little concern to us. Assuming that there are 30 students enrolled for a typical class, use the central limit theorem to calculate the following:

   •   What would be the shape of the distribution of the average class grade of these 30 students?

   •   What would be the average class average of these 30 students be?


   •   What would the standard deviation of the class average be for these 30 students?
