A city contains 100,000 people (45,000 male and 55,000 females), and 1,000 people die per year (600 males and 400 females). There were 50 cases (40 males and 10 females) of lung cancer per year of whom 45 died (36 males and 9 females).
Using this information compute:
1. The crude mortality rate per 1,000
2. The sex-specific mortality rate per 1,000
3. The cause-specific mortality rate per 1,000 for lung cancer
4. The case fatality rate for lung cancer
5. The proportionate mortality ratio for lung cancer
