In a survey of 300 individuals for their response for a new product, 165 gave a positive response, 25 were non-committal and the rest gave a negative response. The point estimate of the proportion of the population who gave a positive response is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 0.55
The point estimate of a population proportion is the sample proportion:
\( \displaystyle \hat{p} = \frac{\text{number with a positive response}}{\text{sample size}} = \frac{165}{300} = 0.55 \)
The non-committal and negative responses are not counted as positive.
