In a certain presidential election, Alaska's 40 election districts averaged 1,958.8 votes per district for a candidate. The standard deviation was 572.5. (There are only 40 election districts in Alaska.) The distribution of the votes per district for one candidate was bell-shaped. Let X = number of votes for this candidate for an election district. O Part (a) State the approximate distribution of X. (Enter your numerical values to one decimal place.) X- N C O Part (b) Is 1,958.8 a population mean or a sample mean? How do you know? O A population mean, because all election districts are included. O A population mean, because only a sample of election districts are included.
