exp(8k- e) ん! 3. Let X be a discrete RV modeled by px(k; B) - for k 0,1,2,.... Here, exp(y) just means e' and is a nice way to show exponents when the expression for y is complicated or has exponentiation in it. If Xi, X2,... , Xn is iid based on X, find the MLE for B
2. Find the MLE for the discrete RV given in problem 5 of HW2 (using the particular data indicated in that problem). Then, explain why your answer for the MLE cannot be surprising (like it was on HW2). You should also draw a picture of the likelihood and log-likelihood (on the same axes) in Desmos and copy your Desmos inputs and picture into your solutions. Thinlk carefully about the domain of this graph x=1 5. Suppose a discrete RV is...
MLE = Maximum Likelihood Estimator
5. Suppose X is a contimmous RV modeled by f(a:a) - el-al where -ox < < oo. If a random sample of size n is drawn with n odd, show the MI for α is the median of the sample.

binomial RV B(n,p) 2. Simulating a Binomial RV. One procedure for generating uses n EXi is binomial if realizations of a uniform random variable and exploits the fact that Y the Xi are Bernoulli RVs. Here is an alternative procedure that requires generating only a single (!) uniform variate: 1/p and B 1/(1 p) 0) Let 1) Set 0 U[0, 1] 2) Generate 3) If k n, go to step 5; else, k ++ au; if u B(u- p). Go...
