A Parks and Recreation official surveyed 200 people at random who have used one of the city's parks. The survey revealed that 26 resided outside the city limits. If she had to arrive at one single value to estimate the true proportion of park users who are residents of the city it would be 0.13.

The survey revealed that 26 out of 200 park users resided outside the city limits, which means that 174 (200 - 26) resided within the city limits. Therefore, the estimated proportion of park users who are residents of the city is 174 / 200 = 0.87, not 0.13.
