Carcinogenic risk level of 1×10-3 is of critical importance because risks above this level require special environmental management actions.  Assuming the risks are distributed normally, the risk manager is going to be required to take special action if more than 16% of the population has risk >1×10-3.  Decide what is the case by testing the variance.
