Question

A committee is planning a reception and estimated that 30 people will attend. On the day of the reception, 39 people attend. What was the percent error of the estimate? Round your answer to the nearest whole percent.

A. 10%
B. 23%
C. 30%
D. 39%

Answer 1

The percent error of the estimated attendance at the reception is calculated as 30%, which indicates a significant difference between the estimated and actual attendance.

Step-by-step explanation:

To calculate the percent error of the estimate, use the formula:

Percent Error = |(Actual Value - Estimated Value) / Estimated Value| x 100%

Plugging in the numbers:

• Actual Value = 39 people
• Estimated Value = 30 people

Percent Error = |(39 - 30) / 30| x 100% = |9 / 30| x 100% = 0.3 x 100% = 30%

Therefore, the percent error of the estimate rounded to the nearest whole percent is 30% (C).
