Question
Each year the soccer team, Peterson United, plays 25 games at their home stadium. The owner of Peterson United claimed that last year the mean attendance per game at their home stadium was 24500.
The actual total attendance last year was 617700.
Based on the owner’s claim, calculate the total attendance for the games at Peterson United’s home stadium last year.
Calculate the percentage error in the owner’s claim.
Write down your answer to part (b) in the form a × 10k where 1 ≤ a < 10, \(k \in \mathbb{Z}\).
