Suppose the annual expected mortality rate from lymphoma is 4.4 per 100,000 individuals.

a.) in a specific region of 500,000 people, how many deaths are expected to be attributed to lymphoma over a one-year period? Show your work.

b.) The actual (observed) number of deaths attributed to lymphoma in the region was 28 people over a one-year period. What would be the observed/expected ratio for these deaths? Please reduce to the simplest form and show your work.

c.) Of the 28 people that died from lymphoma, it was determined that three times the number of ranchers died from it than people with other occupations. How many rangers died from lymphoma? Show your work.
