Question

Jocelyn estimates that a piece of wood measures 5.5cm. If it actually measures 5.62 cm, what is the percent error of Jocelyn’s estimate?

Answer 1

2.14% error

Explanation:

Use the percent error formula:

| (observed - expected) / expected | x 100

Plug in the observed and expected values:

| (observed - expected) / expected | x 100

| (5.5 - 5.62) / 5.62 | x 100

Calculate:

= 2.14% error

So, the percent error of Jocelyn's estimate is 2.14%
