The city of Hamden received money for improvements of the town’s park. The park committee polled a random sample of 75 residents from the town. Of the 75 residents, 27 would like to see more trees planted in the park. From this information, what can be inferred?
Answer
A
Most residents in the town would like to have more trees in the park.
B
Exactly 36% of the residents in the town would like more trees in the park.
C
About a third of the residents prefer a park improvement of more trees.
D
Residents who use the park the most would like more trees planted.
Explanation
In the random sample, 27 out of 75 residents preferred more trees. Since 27 ÷ 75 = 0.36, about 36% of the sample chose more trees, which is close to one third. A random sample can suggest what residents generally prefer, but it does not show that exactly 36% of all residents do, or reveal the preferences of the people who use the park most.
