## Homework 5

Date Assigned: Tuesday, February 26, 2002
Date Due: Tuesday, March 5, 2002

1. Reading: Continue studying Chapter 2, Sections 2.1-2.4.

2. Please solve the following problems in the text:
Chapter 2: 2.2.3, 2.2.4, 2.2.5 (draw a tree), 2.2.6, and 2.2.9 (in part d, n refers to the number of tries before generating a busy signal).

3. Presentations: You may recall from the course syllabus that each student will have the opportunity to deliver a presentation to the class. We will begin the presentations on March 5. I would like the following students to present their solution to Problem 2.2.9:
Andrew Aurand and Nathan Blagrove
The students will present their solution as a group, so they should get together before class on March 5.

4. Develop a MATLAB simulation program for the salesperson model discussed in class. That is, you should simulate a large number of trials, and determine the probability of at least one successful sale in N sales calls, assuming that the calls are independent and that p is the probability of a successful sale on a call. Perform a simulation for the case of N = 10 calls and p = 0.2. Compare your simulation result with the analytical result, and please submit a printout of your MATLAB program.
