Step 1 :We are given a simple random sample of size \(n=75\) obtained from a population of size \(N=30,000\) with a population proportion \(p=0.6\).
Step 2 :We are asked to find the mean and standard deviation of the sampling distribution of the proportion.
Step 3 :The mean of the sampling distribution of the proportion, also known as the expected value of \(\hat{p}\), is equal to the population proportion \(p\). So, \(\mu_{p}=0.6\).
Step 4 :The standard deviation of the sampling distribution of the proportion is given by the formula: \[\sigma_{\hat{p}} = \sqrt{\frac{p(1-p)}{n} \cdot \frac{N-n}{N-1}}\] where \(p\) is the population proportion, \(n\) is the sample size, and \(N\) is the population size.
Step 5 :Substituting the given values \(p = 0.6\), \(n = 75\), and \(N = 30,000\) into the formula, we can calculate the standard deviation.
Step 6 :The calculated standard deviation of the sampling distribution of \(\hat{p}\) is approximately 0.056499.
Step 7 :So, the final answer is: The standard deviation of the sampling distribution of \(\hat{p}\) is \(\boxed{0.056499}\).
