Business and finance. Julio works as a quality control expert in a beverage
factory. The assembly line that he monitors produces about 20,000 bottles in a
24hour period. Julio samples about 120 bottles an hour and rejects the line 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? I am trying to figure it I divide 1/50 by the 24 hours

If he makes 20,000 per day that's 833.3 per hour.
if he samples 120 bottles an hour and its 1/50 of the sample that dictates the outcome (stop the line) then how many bottles is 1/50 of 120 ? That is of course if 'the line' talked about is one hours production.
If indeed the line is to mean a 24 hour period then it would be 1/50 of the amount of samples in a 24 hour period.
120 x 24 / 50
At the end of the day, are we talking about a one hour sample or a 24 hour sample?
