Document Summary
Write very brief explanations. (a) circle either true or false (and explain/correct if false): The random variable x is the number of heads in 10 independent coin tosses with head probability 0. 4. The random variable y is the number of heads in 10 independent coin tosses with head probability 0. 6. These random variables are independent of each other. Suppose that z = x + y : then z is a binomial random variable with n = 20 and p = 0. 5. Success probability is not the same for all trials. (b) circle either true or false (and explain/correct if false): In a hypothesis test, the p-value is 0. 03. Therefore, there is a 3 percent chance that the null hypothesis is true. The p-value is the probability of observing a test statistic at least as extreme as from the original data given that the null hypothesis is true.
