Answer 2

30 PS4 in the shipment are likely to be defective

Explanation:

We take the estimate from the sample and estimate to all the PS4 in store. This means that we can solve this question using a rule of 3.

From the sample of 50 PS4, 3 are defective. How many are expected to be defective out of 500?

50PS4 - 3 defective

500 PS4 - x defective

`50x = 3*500`

`x = (1500)/(50)`

`x = 30`

30 PS4 in the shipment are likely to be defective
