Explanation:
The percent error is given by the formula:
percent error = (|experimental value - actual value| / actual value) x 100%
where | | represents the absolute value.
Substituting the given values, we get:
percent error = (|5.5 - 5.3| / 5.3) x 100%
percent error = (0.2 / 5.3) x 100%
percent error = 0.0377 x 100%
percent error = 3.77%
Therefore, the percent error of the measurement is approximately 3.8% (rounded to the nearest tenth of a percent).
