Question

Doug estimates that his soccer team will win 7 games this year. The team actually wins 10 games. What is the percent error of Doug’s estimate? Round the percent to the nearest tenth if necessary.

Answer 1

Answer: 30%

Percent error = $\dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%$

Estimated number of games win this year = 7
