Question

A toy manufacturer makes 15,000 toys a year. The company randomly selects 300 of the toys to sample for inspection. The company discovers that there are 5 faulty toys in the sample. Based on the sample, how many of the 15,000 total toys are likely to be faulty?

Answer 1

If it is 5 out of 300, then how much out of 15000? This is proportions and so you have to do 15000*5/300 which is 250

Answer 2

The answer is 250. Out of 300 toys, 5 of them were faulty. 15000 divided by 300 is 50. 50 times 5 is 250
