Question

What is the best point estimate for the population's variance if the sample variance is 38.4? Round your answer to one decimal place, if necessary.

Answer #1

The sample standard deviation (s) is a **point
estimate** of the **population** standard
deviation (σ). The sample mean (̄x) is a **point
estimate** of the **population** mean μ, The
sample **variance** (s^2) is a **point
estimate** of the **population variance**
(σ2).

Therefore, the best point estimate for population variance is 38.4
