Probability Please help
Consider a sarnple of data S = {0,1,1,0, 0 1,1) created by flipping a coin r five times, where 0 denotes that the coin turned up heads and 1 denotes that it turned up tails.1. What is the sample mean for this data? 2. What is the sample variance for this data? 3. What is the probability of observing this data, assuming it was generated by flipping a coin with an equal probability of heads and tails (i.e., the probability...

X,,i e..,5) is a random variable that takes a value 0 when the outcome of coin flip i turned up heads, and 1 when it turned up tails. Assume that the outcome of each of the flips does not depend on the outcomes of any of the other flips. The sample obtained S - (Xi, X2,X3, X, Xs) (1, 1,0,1,0 (a)...

When considering data obtained from flipping one coin four times and obtaining all tails, what will the maximum likelihood approach calculate? (Consider that there are three models possible for this coin toss: 1. A fair coin model. 2. A coin with both sides heads. And 3. A coin with both sides tails. Priors are 1. 99.8%, 2. 0.1%, 3. 0.1%) A. The probability of obtaining all tails, averaged over all possible models (i.e. ((.5)^4 * 0.998) + (0 * 0.001)...

(a) What is the conditional probability that exactly four Tails appear w when a fair coin is flipped six times, given that the first flip came up Heads? (I.e. the coin , then is flipped five more times with Tails appearing exactly lour times.) (b) What if the coin is biased so that the probability of landing Heads is 1/3? (Hint: The binomial distribution might be helpful here.)

An unfair coin has probability of heads equal to p. An experiment consists of flipping this unfair coin n times and then counting the number of heads. a. Let Y; be a random variable which is 1 if the ith flip is heads and 0 if the ith flip is tails, where 1 sisn. Show that E (Y) = p and V(Y) = p-p2. b. Derive the moment-generating function of Y. c....

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...

28. In many problems about modeling count data, it is found that values of zero in the data are far more common than can be explained well using a Poisson model (we can make P(X 0) large for X ~ Pois(A) by making λ small, but that also constrains the mean and variance of X to be small since both are X). The Zero-Inflated Poisson distribution is a modification of the Poisson to address this issue, making it easier to...

answer all parts to this 4 part question
Suppose you have a six sided die. One face is printed with the number 1. Two faces are printed with the number 2. Three faces are printed with the number 3. You also have 3 coins: C_1, C_2, and C_3. C_1 will land Heads with probability 1/5. C_2 will land Heads with probability 1/3. C_3 will land Heads with probability 1/2. You roll the die. If the die lands with a...

The next four questions (5 to 8) refer to the following: An unfair coin is tossed three times. For each toss, the probability that the coin comes up heads is 0.6 and the probability that the coin comes up tails is 0.4. If we let X be the number of coin tosses that come up heads, observe that the possible values of Xare 0, 1, 2, and 3. Find the probability distribution of X. Hint: the problem can be solved...
