What occupations do you think might be associated with higher rates of cancer? What about these occupations might create higher cancer rates?

ames has conducted an occupational cohort study. He has studied coal miners and their rates of cancer, and has compared them to steel workers, and their rates of cancer. There were 50 coal miners and 20 steel workers. 25% of steel workers got cancer and 40% of coal miners got cancer. Please draw a 2 by 2 table that represents this scenario.                                 What is the AR?   What is the OR?   Please interpret the OR and make sure to state a time frame ) What is the CIR?

22 A study was conducted to see how people respond to medical statistics. Each subject was given the following descriptions of three screening tests for cancer. If you have this test every 2 years, it will reduce your chance of dying from cancer A by around one third over the next 10 years. Test A: Test B: If you have this test every 2 years, it will reduce your chance of dying from cancer B from around 3 in 1,000 to around 2 in 1,000 over the next 10 years. Test C: If around 1,000 people have this test every 2 years, 1 person will be saved from dying from cancer C every 10 years. a. One of these describes the number needed to treat cancer (see Extensions Task 21). Which one? b. One describes the absolute risk reduction. Which one? SUBTRACT c. One describes the relative risk. Which one? X Greater
