Question 103793: Julio works as a quality control expert in a beverage factory. The assembly line that he monitors produces about 20,000 bottles in 24-hour period. Julio samples 120 bottles an hour and rejects the line if 1/50 of the sample is defective. About how many defective bottles should Julio allow before rejecting the entire line?
I tried to mutiply 120 by 1/50. I am not sure where to start on this one. Answer by stanbon(57203) (Show Source):
