Integer Programming
Introduction
When one or more variables in an LP problem
must assume an integer value we have an
Integer Linear Programming (ILP) problem.
ILPs occur frequently

Examples:
1. An orange juice producer buys all his oranges from a large orange orchard. The
amount of juice squeezed from each of these oranges is assumed to be normally
distributed with a mean of 4.7

Confidence Interval Estimation
There are two types of estimates for unknown population parameters:

Examples:
1. A representative of a community group claims that the average income per
household in the area is $25,000. Suppose that for the type of area involved
household income can be assumed to be
Suggested Solutions
1. Let X = household income
1 = first community
2 = second community
H0: 1 2 = 0
H1: 1 2 0
= 5%
Both population distributions are normal Sampling distribution of ( X 1 X 2 ) is no
Examples:
1. A developer is considering two alternative sites for a regional shopping center.
Since household income in the community is one important consideration in such
site selection, he wishes t

Two-Sample Tests and One-Way ANOVA
In Topics 8 and 9, we learned how to obtain confidence intervals and perform hypothesis tests for one population parameter (, , or 2).

H1: 25000
= 5%
