Suppose that each of two statisticians, A and B, independently takes a random sample of 20 observations

Question:

Suppose that each of two statisticians, A and B, independently takes a random sample of 20 observations from the normal with unknown mean μ and known variance 4. Suppose also that statistician A finds the sample variance in his random sample to be 3.8, and statistician B finds the sample variance in her random sample to be 9.4. For which random sample is the sample mean likely to be closer to the unknown value of μ? Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
