I have the following tables in a relation:

person(ssn,sex) employment(ssn,workweeksperyear)

assume ssn is a key.

My assignment was to do this:

Given as input the number of weeks per year a person has worked, determine whether there are more males than females who work more weeks than the input value.

SELECT COUNT(sex) AS NumMales 
FROM person 
WHERE sex = 'Male' AND ssn IN (SELECT ssn 
                               FROM employment 
                               WHERE workweeksperyear > 48); 

The above query gets me the number of males for an input value and I could do the same for number of females but how do I compare the 2 results?

Any help will be greatly appreciated!
