In a survey question for a sample of 340 people, 85 persons gave positive response, 145 people gave negative response and 110 people were neutral, gave no response. What is the point estimate of the proportion in the population who respond positive?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 0.25
The point estimate of a population proportion is the sample proportion, that is the positive responses divided by the whole sample of 340.
\( \displaystyle \hat{p}=\frac{85}{340} \)
\( \displaystyle =0.25 \)
