Two types of coins are produced at a factory: a fair coin and a biased one that comes up heads 60 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 550 or more times, then we shall conclude that it is a biased coin, whereas if it lands on heads less than 550 times, then we shall conclude that it is a fair coin. Use a normal approximation to compute the following probabilities (ignore continuity correction). (i) If the coin is actually fair, what is the probability that we shall reach a false conclusion? [7] (ii) If the coin is actually unfair, what is the probability that we shall reach a false conclusion? [8] Your
