During 1988, a total of 241 cases of a disease were reported from a community having a population of 40,000. Of the 241 cases, 44 occurred during the period of January through March; 61 occurred during the period of April through June; none during July through September; and 136 during October through December. Further investigation revealed that 76 cases involved males and the rest females. The number of males in the community was 18,500. 1. Calculate the proportional distribution of cases by season. 2. Determine the ratio of male cases to female cases. 3. Calculate the proportional distribution of the cases by sex. A county contains 200,000 people (95,000 males and 105,000 females) and 2, 100 people die per year (1,200 males and 900 females). There are 95 cases (65 males and 30 females) of lung cancer per year of which 65 died (50 males and 15 females). Calculate the following. 4. Male to female ratio 5. Crude death rate per 100,000 6. Gender specific death rates per 1,000 365 cases of disease were reported from a community having a oh
