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?

I know we are supposed to estimate, but I am very confused about the problem. Pplease help me by showing your work.

1/50 * 120 = ?

so would it be 3 bottles an hour, so around 72 bottles?

1/50 * 120 = 120/50 = 2.4
About how many defective
bottles should Julio allow before rejecting the entire line?
He should allow only 2 defective before he rejects the entire line.
