2. John has a special coin and he claims that it lands head 67% of the time it is tossed.

a. What is the probability that in 22 tosses, the coin would land heads 13 or fewer times?

b. If John actually tossed the coin 22 times and obtained 13 heads, would you have a good reason to doubt that John’s claim (head lands head 67% of the time) is true? Explain your answer.

A player tosses a fair coin n times. Each time, if the coin lands on Head, the player win a dollar, otherwise, the player loses a dollar. What is the expected earning of the player? What is the variance of the earning of the player? Now the player apply a new strategy: the player will play the game until he gets a head. What is the expected earning of the new strategy? Does the result depend on n?

- Your friend claims he has a fair coin; that is, the probability of flipping heads or tails is equal to 0.5. You believe the coin is weighted. Suppose a coin toss turns up 15 heads out of 20 trials. At α = 0.05, can we conclude that the coin is fair (i.e., the probability of flipping heads is 0.5)? You may use the traditional method or P-value method.

Is this coin balanced? While he was a prisoner of war during world war 2, John Kerrich tossed a coin 10,000 times. He counted how many times he got heads. a. Is this setting binomial? Explain using the four characteristics of a binomial setting. b. He got 5067 heads. if the coin is perfectly balanced, the probability of a head is 0.5. Is there reason to think that Kerrich’s coin was not balanced? To answer this question, find the probability...

Take a coin that lands “heads” with probability 1/2 and flip it repeatedly while keeping trackof the pattern of “heads” and “tails” that you see. Use 1 to denote a “head” and 0 to denotea “tail”. We are interested in computing the frequency of the pattern{1, 1, 0}, i.e., of seeingtwo consecutive “heads” followed by a “tail”. To do this we construct a Markov chain whosestate space consists of all the possible 3-flip patterns:1){1, 1, 1}2){1, 1, 0}3){1, 0, 1}4){0,...
