**Question 21**Random samples of size 525 are taken from an infinite population whose population proportion is 0.3. The standard deviation of the sample proportions (i.e., the standard error of the proportion) is ____.- ○ 0.2100- ○ 0.0004- ○ 0.0200- ○ 0.3000This question asks for the standard deviation of the sample proportions, known as the standard error of the proportion. This is calculated using the formula:\[SE = \sqrt{\frac{p(1-p)}{n}}\]where \( p \) is the population proportion and \( n \) is the sample size. Given:- Population proportion (\( p \)) = 0.3- Sample size (\( n \)) = 525Use the formula to calculate the standard error.

We have given that, Sample size (n) = 525 and population proportion (p̂) = 0.3 Then, We will find…

When asked: "What is the distribution of X ? X ~ N(___,___)." This notation is referring to N, a normal distribution, with the mean given in the first space and the standard deviation in the second space. Remember that the standard deviation of the sample means is different from the population standard deviation.
