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
