Consider the sample space of outcomes of two throws of a fair die. Let Z = be the minimum of the two numbers that come up. List all the values of Z. Compute its probability distribution. Consider the sample space of outcomes of two tosses of a fair coin. On that space define the following random variables: X = the number of heads; Y = the number of tails on the first toss. For...

Problem 4 (Poisson Distributed RV) In a composite experiment, Z is a Poisson-distributed RV with parameter A, i.e P(Z k, and a coin with probability p of showing heads is tossed Z times (after observing Z). Let X denote the number of heads and Y denote the number of tails after Z tosses (a) Clearly specify the sample space 2xy, the set of values taken jointly by X and Y.

A5 Consider an experiment where you toss a coin as often as necessary to turn up one head. Suppose that the probability of having a tail is p (obviously probability of a head is 1 - p). Assume independence between tosses. a) State the sample space. b) Let X be the number of tosses needed to get one head. What is the support (possible values of X)? c) Find P(X = 1), P(X = 2) and P(X = 3). d)...

2. Suppose we want to test whether a coin is fair (that is, the probability of heads is p = .5). We toss the coin 1000 times, and record the number of heads. Let T denote the number of heads divided by 1000. Consider a test that rejects the null hypothesis that p=.5 if T > c. (a) Write down a formula for P(T>c) assuming p = 0.5. (This formula may be compli- cated, but try to give an explicit...
