Question

A random sample of 50 was taken from a shipment of 12,000 light bulbs. There were 2 broken bulbs in the sample. How many broken bulbs would you expect in the entire shipment?

Answer 1

You can Expect 480 broken bulbs.

Explanation:

The first step is to convert the random sample of broken bulbs to a fraction. The fraction 2/50=0.04

Then, you take 0.04 and multiply it by 12,000. This gets you 480 broken bulbs estimated.

`(2)/(50) =0.04`

`0.04 * 12,000=480`
