Example: Suppose we flip a coin 4 times and count the number of heads.
a) What is the probability of getting exactly 3 heads ? b) Suppose you are told that the first flip came up heads. How would you update your probability of getting exactly 3 heads ? c) What is the probability of the first flip being a head if you are told that the total number of heads was 3 ?

Suppose we flip a coin 100 times independently and we get 55 heads. (a) Test H0 : p = 0.5 versus HA : p > 0.5. Report the test statistic and p-value. Make a decision using α = 0.1. (b) Suppose the decision rule is to reject H0 if ˆp > 0.6. What is the probability of a type I error? If the true value of p is 0.7, then what is the probability of a type II eror?

Conducting a Simulation For example, say we want to simulate the probability of getting “heads” exactly 4 times in 10 flips of a fair coin. One way to generate a flip of the coin is to create a vector in R with all of the possible outcomes and then randomly select one of those outcomes. The sample function takes a vector of elements (in this case heads or tails) and chooses a random sample of size elements. coin <- c("heads","tails")...

(a)Assuming that we toss a in-balanced coin for 100 times, and we get 40 heads from our experiment. Assuming that the relative frequency is just the true probability for tossing to get a head. Then we want to know: Probability for getting a head:   Expected variance if tossing 70 times:   (b)Given a poisson distribution with expectation 4, so the standard deviation of this distribution should be
