If you select a random sample of 100 voters, what is the probability that a candidate will be forecast as the winner when
a) The true percentage of her vote is 50.1%?b) The true percentage of her vote is 60%?c) The truce percentage of her vote is 49% (and she will actually lose the election)?d) If the sample size is increased to 400, what are your answers tp (a) through (c)? Discuss.
