A random sample of size 4 is taken with replacement from a population with population mean of 12 and population variance of 8. What is the variance of the sampling distribution.
Given, Population mean "\\mu=12" , population variance "\\sigma^2=8"
sample size "n=4"
Sample standrad deviation "s= \\sqrt{\\sigma^2}\\times \\sqrt{n}=\\sqrt{8}\\times \\sqrt{4}=\\sqrt{32}"
Variance of sampling Distribution "s^2=(\\sqrt{32})^2=32"
