Can anyone help me with a word problem?

I have to put this information in a formula and show my work.

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?

Any help will be appreciated.

Well, the first part is not really important is it? It doesn’t matter how many bottles are produced in a 24 hour period. 20000 in 24 hours is 833.33. Doesn’t matter though. the question asks for the number of sampled bottles allowed before he must reject. 120 sampled bottles per hour. 1/50th of 120 is 2.4. so I would say the answer is 2 bottles allowed per hour. 3 bottles would be over.

He needs to stop the line if more than1/50 of the SAMPLE is found defective. 1/50=2% 2% of 120 is 2.4 bottles.

Therefore, 2 defective bottles are OK; 3 defects will exceed the 2% and require a line stop.

What is the lowest number greater than 1/50 of the number of samples?

Divide 120 by 50 and increase that to the next greater whole number.

i’m not sure, but:

hours of assembly = 24

120 bottles an hour * hours of assembly = number of sampled bottles for the whole line

(1/50)(number of sampled bottles) = number of bottles needed to reject the whole line

if you solve all that, you’ll get 57.6, or 58.

3 bottles

1/50=x/120

x=2.4

so it has to be more than
