To determine the percentage error, we need to calculate the absolute error and then divide it by the measured value (8.67kg) and multiply by 100.
Absolute error = measured value - actual value
Since the actual value is not given, we will assume that the actual value is the nearest possible value to the measured value, which would be 8.665kg (since the digit after the tenths place is 7, which is equal to or greater than 5).
Absolute error = 8.67kg - 8.665kg = 0.005kg
Percentage error = (Absolute error / Measured value) x 100
= (0.005kg / 8.67kg) x 100 ≈ 0.0576 x 100 ≈ 5.76%
Therefore, the percentage error in this measurement is approximately 5.76%.
