A learning experiment requires a rat to run a maze (a network of pathways) until it locates oneof three possible exits. Exit 1 presents a reward of food, but exits 2 and 3 do not. (If the rateventually selects exit 1 almost every time, learning may have taken place.) Let Y; denote thenumber of times exit i is chosen in successive runnings. Assume that the rat chooses an exit atrandom on each run. Find the probability that n = 3 runs result in Y, = 1, Y2 = 1, and Y3 = 1.

A rat runs in a maze with three exits. The rat eventually always chooses exit 1 where reward of food…

In the Chernobyl nuclear accident it is estimated that 30,000 people received an average dose of 45 REM. For this population, using the linear hypothesis, how many "normal" deaths from cancer are expected and how many additional deaths from the radiation of the accident? Group of answer choices 500 normal, 6000 additional 1000 normal, 4000 additional 2000 normal, 3000 additional 4000 normal, 1000 additional 6000 normal, 500 additional
It is claimed that a vitamin supplement helps mice learn to run a maze more quickly and, in fact, to beat a non-treated mouse 70% of the time (whereas without the supplement, it would only win half of the time). To test this claim, you divide a group of 20 mice randomly into ten pairs, giving one of each pair the vitamin supplement. You run each pair through the maze and find that seven out of ten of the mice treated with the vitamin supplement beat the untreated mice. a) What is the probability of obtaining this result if the claim is true? b) What is the probability of obtaining this result if the claim is false (i.e., the supplement has no effect)? c) Suppose before you ran this experiment, you thought it was equally likely that the claim was true or false. After running the experiment, what is your belief? What is the updated probability?

Assume that we have three coins: The first coin is fair. The second coin is unfair with probability of heads equal to 0.8. The third coin is also unfair with probability of heads equal to 0.3. Consider an experiment involving two successive coin tosses. The result of the first stage of the experiment is determined by the toss of the fair coin. The result of the second stage of the experiment is determined by the toss of a coin, but suppose that the coin that is used depends upon the result of the toss of the fair coin. Specifically, if the toss of the fair coin results in heads, then the second coin is tossed. Otherwise the third coin is tossed. Let Hi and Ti be the events that ith toss resulted in heads and tails, respectively. Answer the following questions. a) Give a sequential description of the experiment using a tree diagram. b) Calculate the probabilities of the possible outcomes of the experiment. c) Calculate P(H2) d) Are the events H1 and H2 independent?

Jack has just been given a ten-question multiple choice quiz in history class. Each question has five answers, of which only one is correct. Since Jack has not attended class recently, he does not know any of the answers. Assuming Jack guesses randomly on all ten questions, find the probability that he will answer six or more of the questions correctly and avoid an F.

Assume that we have three coins: The first coin is fair. The second coin is unfair with probability of heads equal to 0.8. The third coin is also unfair with probability of heads equal to 0.3. Consider an experiment involving two successive coin tosses. The result of the first stage of the experiment is determined by the toss of the fair coin. The result of the second stage of the experiment is determined by the toss of a coin, but suppose that the coin that is used depends upon the result of the toss of the fair coin. Specifically, if the toss of the fair coin results in heads, then the second coin is tossed. Otherwise the third coin is tossed. Let H, and T, be the events that ith toss resulted in heads and tails, respectively. Answer the following questions. Calculate P(H,). Are the events H, and H, independent? Justify your answer analytically.
