Question

Based on the time recorded for 700 attendees at an amusement park, the average amount of time spent at the park was 7.25 hours with a margin of error of ±1.65 hours. If 3,000 people attended the park on a given day, what is the estimated range of total hours the attendees spent in the park?

8,375 to 16,800 total hours spent in the park
16,800 to 21,785 total hours spent in the park
16,800 to 26,700 total hours spent in the park
16,800 to 35,885 total hours spent in the park

Answer 1

C, 16,800 to 26,700 total hours spent in the park.

Explanation:

Formula: (Hours Per Person) minus (Margin of Error) = result

result x (The Number of People)

(Hours Per Person) plus (Margin of Error) = result

result x (The Number of People)

Insert the numbers into the formula,

7.25 - 1.65 = 5.6

5.6 x 3000

= 16,800 (minimum)

7.25 + 1.65 = 8.9

8.9 x 3000 = 26700 (maximum)

Answer 2

The answer is C. 16,800 to 26,700 total hours spent in the park.
