Exercise 6.8.6 In the 1992 presidential election, Alaska's 40 election districts averaged 1956.8 votes per district for President Clinton. The standard deviation was 572.3. (There are only 40 election districts in Alaska.) The distribution of the votes per district for President Clinton was bell-shaped. Let X = number of votes for President Clinton for an election district. (Source: The World Almanac and Book of Facts) a. State the approximate distribution of X. X b. Is 1956.8 a population mean or a sample mean? How do you know? c. Find the probability that a randomly selected district had fewer than 1600 votes for President Clinton. Sketch the graph and write the probability statement. d. Find the probability that a randomly selected district had between 1800 and 2000 votes for President Clinton. e. Find the third quartile for votes for President Clinton.
