Answer:
30 PS4 in the shipment are likely to be defective
Step-by-step 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](https://tex.z-dn.net/?f=50x%20%3D%203%2A500)
![x = \frac{1500}{50}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1500%7D%7B50%7D)
![x = 30](https://tex.z-dn.net/?f=x%20%3D%2030)
30 PS4 in the shipment are likely to be defective
