Final answer:
The percent error from 16 lbs to 13 lbs is approximately 18.75%.
Step-by-step explanation:
The percent error can be calculated using the formula:
Percent Error = | (Experimental Value - Accepted Value) / Accepted Value | x 100%
In this case, the experimental value is 13 lbs and the accepted value is 16 lbs.
Plugging these values into the formula:
Percent Error = | (13 - 16) / 16 | x 100%
Percent Error = | -3 / 16 | x 100% = 18.75% (rounded to two decimal places)
So, the percent error from 16 lbs to 13 lbs is approximately 18.75%.
