The manufacturer finds that 10% of the flashlights in a sample are defective. Predict how many defective flashlights there would be in a shipment of 4,000 flashlights?

Answer 1

There would be 400 defective flashlights in a shipment of 4,000 flashlights.

To find this answer, you can use the following calculation:

Number of defective flashlights = 10% of 4,000

Number of defective flashlights = 0.10 x 4,000

Number of defective flashlights = 400
