The supervisor at the bottle factory took a random sample of 17 bottles
manufactured by machine A. He found that 1 bottle in this sample was
defective. If machine A produces 3125 bottles per day, based on the
supervisor's sample about how many defective bottles are produced by machine
A per day?
A) 184
B) 199
C) 189
D) 194

Sagot :

Answer: A) 184

Explanation:
Out of 17 bottles from the sample, 1 of them were defected, we are left with a fraction of 1/17 of cups out of the total would be defected. We multiply that fraction with the 3125 bottles that machine A produces to find how many defected bottles are produced by it a day.

(1/17) x 3125 = 183.8

The answer is 183.8, after rounding to the nearest one, the answer is 184.
