The attendance 40 basketball game was estimated to be 15,000 people for 12,500 people attended what was the percent error?

Percent error formula is used to calculate the precision of calculations. The formula is as follows:

Here, calculated value is experimental value and the known value or accepted value is theoretical value.

Here, the attendance was estimated to be 15,000 people, but the exact attendance is 12,500 people thus, 15,000 is theoretical value and 12,500 is experimental value. Percent error in attendance is calculated as follows:

Thus, percent error is 16.66%.
