In a survey for a sample of 300 individuals, 180 persons gave responses 'Yes' and 100 gave responses 'No' and 20 gave "No response". Then point estimate of proposition in the population who responded "Yes" is

0.6

The correct answer is Option (3) → 0.6

Total sample: $n = 300$

Number of "Yes" responses: $x = 180$

Point estimate of proportion of "Yes" in population:

$\hat{p} = \frac{x}{n} = \frac{180}{300} = 0.6$
