If the standard error of the sampling distribution of sample proportions is 0.0245 for samples of size 400,then the population proportion must be 0.40.

Question

Quizplus · Accepted Answer

The standard error of the sampling distribution of sample proportions depends on the population proportion (p) and the sample size (n), and is given by the formula sqrt[p(1-p)/n]. Therefore, knowing only the standard error and the sample size does not allow us to determine the population proportion with certainty.
