Assignment 9 - due October 17

In a recent article it is claimed that a single CT scan would increase the chances of dying from cancer by 1 in 2,000. When compared to the overall risk of dying from cancer (about 400 in 2,000, or 20%) this doesn't seem like a large risk. But . . . . . .

  1. Take the data you found from assignment 1 and estimate the extra number of cancer deaths in the US per year.
  2. If the average lifespan of a US citizen is 80 years how many total extra deaths might be expected?
  3. Do you think that this number of extra deaths is acceptable for the economic beniefits that are being projected?
