If the mortality is based upon the total population it would include non-smokers who get lung cancer less often than smokers. That would artificially decrease the mortality rate in smokers.

Or how about prostate cancer. If we used total population to determine the mortality rate of prostate cancer it would include women who do t even have a prostate.

Also, do we really know the true population?  Someone do a head count?

Ask him to do a two way t test with p-hat.
