Textbook Question

Chapter 9.1, Problem 21E

Political Polls: Morris Polling conducted a poll 6 months before an election in a state in which a Democrat and a Republican were running for governor and found that 60 % of the voters intended to vote for the Republican and 40 % intended to vote for the Democrat. A poll conducted 3 months later found that 70 % of those who had earlier stated a preference for the Republican candidate still maintained that preference, whereas 30 % of these voters now preferred the Democratic candidate. Of those who had earlier stated a preference for the Democrat, 80 % still maintained that preference, whereas 20 % now preferred the Republican candidate.

a . If the election were held at this time, who would win?

b . Assuming that this trend continues, which candidate is expected to win the election?
