Suppose you take a 15 question true or false quiz and you guess on every problem. you only get 3 correct. (a) what is the probability of getting 3 or fewer correct guesses? round your answer to 3 decimal places. (b) would 3 be an unusually low number of correct guesses? use the criteria that a number (x) is unusually low if p(x or fewer) ≤ 0.05. yes, that is an unusually low number of correct guesses. no, that is not an unusually low number of correct guesses.
