(Step-by-Step) Let X ~ BIN (n,p) and p hat = X/n. Find a constant c so that E[c(p hat)(1-p hat)] = p(1-p). Find an unbiased estimator of Var (X). Consider a random
Question: Let X ~ BIN (n,p) and p hat = X/n.
- Find a constant c so that E[c(p hat)(1-p hat)] = p(1-p).
- Find an unbiased estimator of Var (X).
-
Consider a random sample of size N from BIN (n,p). Find unbiased estimators of p and Var (X) based on the random sample.
