Here is my question: 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 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 = 2 2/5
Since he needs to find more than 2 2/5 defective bottles, he should reject the entire line when he finds that 3 are defective.
