Final answer:
The percent error of the experiment comparing the average measured weight of the swans to the actual healthy swan weight is calculated by taking the difference of the actual and measured values, dividing by the actual value, and multiplying by 100%. The result is a percent error of 18.75%. The correct answer is option b. 18.75%
Step-by-step explanation:
The student has provided data about an experiment where the average measured weight of swans was compared to the known healthy weight to calculate the percent error. The correct answer is determined by using the formula for percent error where actual value is compared to the measured value.
To calculate the percent error of the experiment, you subtract the actual value from the measured value, divide by the actual value, and then multiply by 100 to get a percentage. Using the numbers provided (16 lbs for actual weight and 13 lbs for measured weight), the calculation is as follows:
Percent Error = ((Actual Value - Measured Value) / Actual Value) × 100%
Percent Error = ((16 - 13) / 16) × 100%
Percent Error = (3 / 16) × 100%
Percent Error = 0.1875 × 100%
Percent Error = 18.75%
The percent error of the experiment comparing the average measured weight of swans to the actual healthy swan weight is 18.75%, which corresponds to option b.
