**Problem Statement:**

Suppose we observe \( X_1, X_2, \ldots, X_n \sim \text{iid } Ber(p) \) and let \( \bar{X}_n \) be the sample average. Suppose we want to estimate the variance \( g(p) = p(1-p) \).

1. Consider estimator \( g(\bar{y}_n) = \bar{y}_n (1 - \bar{y}_n) \). Is it consistent for \( g(p) \)? Why?

2. Assuming \( p \neq 1/2 \), find the distribution of \( \sqrt{n} \left( g(\bar{y}_n) - g(p) \right) \) as \( n \to \infty \).
