2.Joe found an old copy of the Guinness Book of World Records. It stated that there are on average 138 marriage licenses issued in Las Vegas per day in 2005 during the open hours of the licensing office. The licensing office is open from 9:00 am to 9:00 pm. Let Mbe the number of marriage licenses in an hour on a day in 2005. a)What are the distribution, parameter(s), and support of M ? b)What is the average and standard deviation of the number of marriage licenses issued in one hour? c)What is the probability that between 10 and 12 (inclusive) marriage licenses will be issued in an hour? ?(10 ≤ ? ≤ 12) = ?(? = 10) + ?(? = 11) + ?(? = 12) d)One of the clerks has been tracking the licenses issued for every one hour increment a particular day. What is the probability that between 10 and 12 (inclusive) marriage licenses will be issued in 6 of those one-hour increments. State the distribution and parameter(s) you are using. e)What is the probability that the 4thhour that the license office is open, is the first one with between 10 and 12 (inclusive) marriage licenses issued? Let Y be the first hour with between 10 and 12 marriages licensed issued 3.At the Statistics Department Annual Party, there is a graduate student raffle for 7 prizes. Each graduate student is provided one ticket. There 85 tickets distributed to all of the graduate students. Tallis is a new student and really wants to win. He asks his friends to give them their tickets. Tallis ends up with 4 tickets. Each of these tickets will either win a prize or not win a prize. (note: think about the sample size.) a)The announcer reveals the winning tickets. Let Wbe the number of winning tickets Tallis has. What is the probability he wins at least one prize. What is the distribution, parameter(s), and support of W ? (
