Answer:
The percent error is 4.81%.
Explanation:
There is a mistake in a question, hence it is corrected below:
Jocelyn estimates on a piece of wood measures 5.45 cm if it actually measures 5.2 cm.
Now, to find the percent error.
Estimation of Jocelyn = 545 cm.
Wood actually measures = 5.2 cm.
So, to get the measurement error we subtract wood actually measures from estimation of Jocelyn:

Thus, the error in measurement = 0.25 cm.
Now, to get the percent error:



The percent error of Jocelyn's estimate is 4.81%.
Therefore, the percent error is 4.81%.
