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. State the approximate distribution of X. X - N( Is 1,956.8 a population mean or a sample mean? (population/sample) Find the probability that a randomly selected district had fewer than 1,600 votes for President Clinton. (Sketch the graph and write the probability statement.) The probability that a district had less than 1,600 votes for President Clinton is Find the probability that a randomly selected district had between 1,800 and 2,000 votes for President Clinton. 0.2662 Find the third quartile for votes for President Clinton. Seventy-five percent of the districts had (more/fewer) than votes for President Clinton. QUESTION 12 Terri Vogel, an amateur motorcycle racer, averages 129.71 seconds per 2.5 mile lap (in a seven-lap race) with a standard deviation of 2.28 seconds.
