1-What is Implementation, why is it important?
2- Katherine is planning to finance her college education by selling programs at football games for State University. There is a fix cost of $400 for printing these programs, and the variable cost is $3. There is also $1,000 fee paid to the university for the rights to sell these programs. If Katherine was able to sell programs for $5 each, How many would she have to sell in order to break even?
3- an urn contains 8 red chips, 10 green chips and 2 white chips. A chip is drawn and replaced, and a second is drawn. what is the probability of
(a) a white chip on the first draw?
(b) a white chip on first draw and a red on the second?
(c) two green chips being drawn?
(d) a red chip on the second, given that a white chip was drawn on the first?
4- Read WTVX case study and answer the associated discussion questions.
WTVX, Channel 6, is located in Eugene, Oregon, home of the University of Oregon's football team. The station was owned and operated by George Wilcox, a former Duck (University of Oregon football player). Although there were other television stations in Eugene, WTVX was the only station that had a weatherperson who was a member of the American Meteorological Society (AMS). Every night, Joe Hummel would be introduced as the only weatherperson in Eugene who was a member of the AMS. this was George's idea, and he believed that this gave his station the mark of quality and helped with market share.
In addition to being a member of AMS, Joe was also the most popular person on any of the local news programs. Joe was always trying to find innovative ways to make the weather inter¬esting, and this was especially difficult during the winter months when the weather seemed to remain the same over long periods of time. Joe's forecast for next month, for example, was that there rwould be a 70% chance of rain every day, and that what happens on one day (rain or shine) was not in any way dependent on what happened the day before.
One of Joe's most popular features of the weather report was to invite questions during the actual broadcast. Questions would be phoned in, and they were answered on the spot by Joe. Once a 10-year-old boy asked what caused fog, and Joe did an excellent job of describing some of the various causes.
Occasionally, Joe would make a mistake. For example, a high school senior asked Joe what the chances were of getting 15 days of rain in the next month (30 days). Joe made a quick cal¬culation: (70%) x (15 days/30 days) = (70%)(1/2)= 35%. Joe quickly found out what it was like being wrong in a university town. He had over 50 phone calls from scientists, mathemati¬cians, and other university professors, telling him that he had made a big mistake in computing the chances of getting 15 days of rain during the next 30 days. Although Joe didn't understand all of the formulas the professors mentioned, he was determined to find the correct answer and make a correction during a future broadcast.
Discussion Questions
1. What are the chances of getting 15 days of rain during the next 30 days?
2. What do you think about Joes assumptions concerning the weather for the next 30 days?
