Let X_1,X_2,...,X_n be iid Bernoulli(p). Also let T be Binomial(n, p).

So I found that they both have the same moment generating function, and I found the mean and variance of T. The question asks:

Let n=20 and (x_1+...+x_n)=9. Using the method of moments, find an estimate of theta = log(p/(1-p)).

I'm not sure how to proceed from here.
