Question 415759
In 1984 an internal investigation within major New York metropolitan hospital was leaked to the New York Herald.
-------------------------------- 
The investigation found that on average out of every 125 medications dispensed there were 2 errors, 
---------------------------
but only 1 in 500 medications dispensed significantly harmed the patient. 
-----------------------
Of those suffering significant harm from medication 
error, 2% died. The hospital at that time dispensed 75,000 medications during the year of this investigation. 

a. What was the expected number of significant errors?
Error rate = 2/125
---
# of errors = (2/125)*75000 = 1200
---------------------------------------------

b. How many died as a result from hospital medication errors? How many are 
expected to have died after a medication error? 
Ans: 0.02*1200 = 24
-----------------------------------------------

c. Out of all medication errors, what is the expected percentage that would result in death?
Ans: 24/1200 = 2%
