Question

A factory produces 1000 bottles of pasta sauce in a day. Fifty bottles are selected at random to determine whether they weigh the correct amount. The factory rejects bottles that are over or under the correct weight.

One bottle is underweight, 46 bottles are the correct weight, and 3 bottles are overweight.

Based on this random sample, approximately how many bottles will the factory reject from the day's production?

Answer 1

Your final answer is :

The factory will approximately reject 80 bottles from the day's production.

Hope I helped :)

Answer 2

Approximately 80 bottles will the factory reject. In the sample of the 50 bottles, one bottle is underweight, three are overweight, so 3+1=4 bottles are not the correct weight and will be rejected. Four out of fifty would be rejected, or one out of 12.5. Therefore, approximately 1000*1/12.5=80 bottles will be rejected.
