Question

A grocery store near Hansen's house had a contest in which customers guessed how many jelly beans were in a glass jug. The closest guess would win a gift card. The actual total was 497 jelly beans, and Hansen's guess of 496 jelly beans made him the winner! What is the percent error for Hansen's guess?

Answer 1

Hansen's guess had a percent error of approximately 0.201%.

Explanation:

Percent Error = [(|Actual Value - Estimated Value|) / |Actual Value|] * 100

Percent Error = [(|497 - 496|) / |497|] * 100

Percent Error = (1 / 497) * 100

Percent Error ≈ 0.201%
