Textbook Question
Chapter 4.1, Problem 68E
Make up a scheduling problem that would be of some interest to you, similar to what we did in Exercise 67. Use graph theory to develop a solution.
Assume that the registrar at your school is building a final exam schedule and because the following courses are known to be particularly difficult, the registrar does not want any student to take finals for two of them on the same day. The courses are Anth215, Bio325, Chem264, Mat311, Phy212, Fin323, and ComD265. The table indicates which courses have students in common and therefore should have their finals on different days. Assume that two courses are related if they have any students in common. Model this set of courses with a graph and use it to design a final exam schedule.
| Course | Has students in common |
| Anth215 | Bio325, Chem264, Mat311, Fin323, ComD265 |
| Bio325 | Chem264, Fin323 |
| Chem264 | Mat311, Phy212 |

In Gallup's Annual Consumption Habits Poll, telephone interviews were conducted for a
random sample of 1014 adults aged 18 and over. One of the questions was, "How many
cups of coffee, if any, do you drink on an average day?" The following table shows the
results obtained (Gallup website, August 6, 2012).

Define a random variable x = number of cups of coffee consumed on an average day. Let
x=4 represent four or more cups.
a. Develop a probability distribution for x.
b. Compute the expected value of x.
c. Compute the variance of x.
d. Suppose we are only interested in adults who drink at least one cup of coffee on an
average day. For this group, let y = the number of cups of coffee consumed on an
average day. Compute the expected value of y and compare it to the expected value of x.
Ten major college football bowl games were played in January 2010, with the University

The predicted winning point margin was based on Las Vegas betting odds approximately
one week before the bowl games were played. For example, Auburn was predicted to beat
Northwestern in the Outback Bowl by five points. The actual winning point margin for Au-
burn was three points. A…
