Correct Answer is : The variance between the class score distribution is significantly different

The variance between the class score distribution is significantly different

The variance between the class score distribution is not significantly different

This test applies only to Normal Distributed data at 99 % confidence

This test applies only to Non-normal Data at 99 % confidence

There are not enough data points to make any statistical conclusions
