Question

While attending a college football game, you think you can guess the attendance within 10% of the actual value. If the announced attendance is 65,000, within what number of people would your guess have to be in order for you to support your claim?

Answer 1

6,500

Explanation:

If you think you can guess the attendance within 10% of the actual value, then your guess would have to be within 6,500 of the actual attendance of 65,000 in order for you to support your claim. This is because 10% of 65,000 is 6,500. So if your guess is within 6,500 of the actual attendance, then you can support your claim.

Answer 2

13,000 People

Explanation:

65,000 (0.1) = 6500

6500 (2) = 13,000

You multiply by 2 to get 10% above or below the announced attendance.
