In a program designed to help patients stop smoking, 219 patients were given sustained care, and 83.6% of them were no longer smoking after one month.

(Hypothesis Testing: Uniform and Uniform) Consider the binary hypothesis testing problem in which the hypotheses H=0 and H=1 occur with probability PH(0) and PH(1)=1- PH(0), respectively. The observation Y is a sequence of zeros and ones of length 2k, where k is a fixed integer. When H=0, each component of Y is 0 or a 1 with probability ½ and components are independent. When H=1, Y is chosen uniformly at random from the set of all sequences of length 2k...
