Unformatted text preview: H ? Problem 3: Suppose we want to test whether a die is fair or not. In particular, we suspect that the probability of getting a six may be greater than 1/6. We roll the die 1000 times, and the number of six we observe is 180. (1) Suppose we x the probability of type I error to be 2 . 5%. Then what is the decision rule? Should we declare that the die is not fair? (2) If the die is indeed not fair, and the probability of getting a six is .2. Calculate the probability of type II error of the decision rule in (1). 1...
