1. The human resource department of the cotton factory asks you to estimate how many people in their factory of 25,000 total workers you expect to develop respiratory disease per year as a result of cotton fiber exposure. How many workers do you anticipate develop a respiratory disease because of their cotton fiber exposure

Complete Question

You are the epidemiology consultant to a cotton fabric manufacturer. Because of some suspicion on the part of local physicians, you conduct a study of the occurrence of respiratory disease among the workers and obtain the following results:

Incidence of respiratory disease among workers exposed to the cotton fiber = 200 per 100,000 per year

Incidence of respiratory disease among workers not exposed to the cotton fiber = 40 per 100,000 per year

Incidence of respiratory disease among general population = 45 per 100,000 per year

How many workers do you anticipate develop a respiratory disease because of their cotton fiber exposure

The number of workers is  

Step-by-step explanation:

From the question we are told that

   The number of worker are  

    The incidence of respiratory disease among workers is  

The number of workers that would contact this disease is mathematically evaluated as

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
