Show all your work for credit on the indicated space, and follow directions. Good luck. 1. Which statistic is the best-unbias

Answer 1

Answer #1

Question 1

Part a

The best unbiased estimator for the population mean µ is the sample mean Xbar.

E(µ) = Xbar

Part b

The best unbiased estimator for the population proportion p is the sample proportion p̂.

E(p) = p̂

Where, p̂ = x/n

x = number of items of interest

n = sample size
