<PRE><B>Question 101043</B>
Julio works as a quality control expert in a beverage
factory. The assembly line that he monitors produces about 20,000 bottles in a
24-hour period. Julio samples about 120 bottles an hour and rejects the line if
he finds more than 1/50 of the sample to be defective. About how many defective
bottles should Julio allow before rejecting the entire line?
---------------
(1/50)*120 = 12/5 = 2.4 bottles /er hour
He should stop the line if he finds 3 defective bottles in an hour.
So he should allow 2 defective per hour.
