The standard error of the sampling distribution of the sample proportion $\hat { p }$ ,when the sample size n = 100 and the population proportion p = 0.30,is 0.0021.

Question

Quizplus · Accepted Answer

The standard error of the sample proportion is calculated using the formula $\sqrt{\frac{p(1-p)}{n}}$. For $p = 0.30$ and $n = 100$, it is $\sqrt{\frac{0.30 \times 0.70}{100}} = 0.0458$, not 0.0021.
