Consider the population consisting of 1,3,5 and 7. Suppose samples of size 2 are drawn from this population. Find the mean and variance of the sampling distribution of the sample means.
Answer:
( solution is chronologically attached above )
Mean of the sampling distribution of the sample means:![\color{red}{3.92} \color{red}{3.92}](https://tex.z-dn.net/?f=%5Ccolor%7Bred%7D%7B3.92%7D)
Variance of the sampling distribution of the sample means:![\color{red}{1.7} \color{red}{1.7}](https://tex.z-dn.net/?f=%5Ccolor%7Bred%7D%7B1.7%7D)
