Most exhibition shows open in the morning and close in the late evening. A study of Saturday arrival times showed that the average arrival time was 2 hours and 2 minutes after the doors opened, and the standard deviation was estimated at about 44 minutes. Assume that the arrival times follow a normal distribution. At what time after the doors open will 55% of the people who are coming to the Saturday show have arrived? 2 hours 13 minutes 2 hours 1 minute O I hour 56 minutes O 2 hours 7 minutes O O hours 5 minutes

In the 1992 presidential election, Alaska's 40 election districts averaged 2008 votes per district for President Clinton. The standard deviation was 573. (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) Round all answers except part e. to 4 decimal places.a. Find the probability that a randomly selected district had fewer than 2096 votes for President Clinton. b. Find the probability that a randomly selected district had between 2047 and 2177 votes for President Clinton.c. Find the third quartile for votes for President Clinton. Round your answer to the nearest whole number.
