Question

Out of a random sample of 330 apples, 25 are rated "AAA." Estimate the number of apples that would be rated "AAA" in a crop of 50,000 apples.

Answer 1

3750 apples

Explanation:

Prob (Apple AAA rating) = AAA rated apples / Total Apples

25 / 330 = 0.075

Expected apples rated AAA from 50000 apples = P(AAA rating) x Apples no.

0.075 x 50000

3750
