Joe Smith plays a betting game with his friends. He puts in one dollar to join the game. If he wins the game, he gets $2. If he loses, he gets nothing, so his gain is –$1. Joe Smith is planning to play the game 100 times. The 100 outcomes will be independent of one another. Let Vi, i = 1, 2, ..., 100 be the 100 outcomes. Then each Vi has the same probability distribution: v -1 1 p(v)...

Joe, a basketball player, claims that he makes at least 60% of his basketball free throws. Assuming that he attempts 20 free throws, use an exact binomial distribution to evaluate Ho: p = 0.6 against a one-sided alternative that his success percentage is lower than 0.6. Let X be the number of free throws made. Which rejection region is the most appropriate for this test and why? ?1 = {?|? ≤ 8} ?2 = {?|? ≥ 16} ?3 = {?|?...
