A company finds 8 bags with faulty zippers in a sample of 500. Predict how many bags with faulty zippers are in a shipment of 20,000?
To predict how many bags with faulty zippers are in a shipment of 20,000, we can use the concept of proportion.
The proportion of bags with faulty zippers in the sample of 500 is:
8/500 = 0.016
This means that 1.6% of the bags in the sample have faulty zippers.
To predict how many bags with faulty zippers are in a shipment of 20,000, we can use this proportion and multiply it by the total number of bags in the shipment:
20,000 x 0.016 = 320
Therefore, we can predict that there may be 320 bags with faulty zippers in a shipment of 20,000. However, this is just a prediction and the actual number may vary.
