According to a November 2008 survey completed by the Pew Internet & American Life Project [www. pewinternet.org], about 74% of all adult Internet users say they went online for news and information about the 2008 election or to communicate with others about the election race. Assuming the percentage is correct, use the normal approximation to the binomial to find the probability that in a survey of 2000 American adult Internet users,
a. at least 1400 used the Internet for information about the 2008 election.
b. at least 1565 used the Internet for information about the 2008 election.
c. at most 1500 used the Internet for information about the 2008 election.
d. at most 1425 used the Internet for information about the 2008 election.
