Two types of coins are produced at a factory: a fair coin and a biased one that comes up heads 55 percent of the time. we have one of these coins but do not know whether it is a fair coin or a biased one. in order to ascertain which type of coin we have, we shall perform the following statistical test: we shall toss the coin 1000 times. if the coin lands on heads 525 or more times, then we shall conclude that it is a biased coin, whereas, if it lands heads less than 525 times, then we shall conclude that it is the fair coin. if the coin is actually fair, what is the probability that we shall reach a false conclusion? what would it be if the coin were biased?
