An airline performed 4000 pre-flight inspections during one month. Each inspection checks 50 items.
(That's 200,000 items checked per month Right?)
problem: What is the maximum number of defects which could occur throughout a year if the process is operating at a six sigma level?
Need help figuring this out? Use the logic below.
a. You are given the number of monthly inspections. How many inspections does which make per year?
b. Now, how many total items are checked per year in those inspections (remember, that's 50 items per inspection)?
c. This total number of items inspected is one million times what factor?
d. Remember how many defective items are anticipated per million opportunities in the Six Sigma?
e. The answer to ‘c’ times the answer to ‘d’ will be your answer to the test problem. What is it?
