hello! please help with my stats homework :)

In a certain presidential election, Alaska's 40 election districts averaged 1,952.8 votes per district for a candidate. The standard deviation was 572.2. (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. El Part (a) State the approximate distribution of X. (Enter your numerical values to one decimal place.) w( 1 ) E Par! ([1) ls 1,952.8 a population mean or a sample mean? How do you know? 0 A population mean, because all election districts are included. O A population mean, because only a sample of election districts are included. 0 A sample mean, because only a sample of election districts are included. 0 Asample mean, because all election districts are included, Find the probability that a randomly selected district had fewer than 1,600 votes for this candidate. (Round your answer to four decimal places.)

(Round your answer to tour decimal places.) :] Find the third quartile for votes for this candidate. (Round your answer up to the next vote.) Ewes
