# Discrete Random Variables: Practice 5: Hypergeometric Distribution

Summary: This module provides further practice and exercises on Hypergeometric Distribution in statistics

Note: You are viewing an old version of this document. The latest version is available here.

## Student Learning Objectives

• The student will investigate the properties of a hypergeometric distribution.

## Given

Suppose that a group of statistics students is divided into two groups: business majors and non-business majors. There are 16 business majors in the group and 7 non-business majors in the group. A random sample of 9 students is taken. We are interested in the number of business majors in the group.

## Interpret the Data

### Exercise 1

In words, define the Random Variable XX.

XX ~

H(16,7,9)

### Exercise 3

XX takes on the values:

2,3,4,5,6,7,8,9

### Exercise 4

Construct the probability distribution function (PDFPDF) for XX.

Table 1
XX P(X=x)P(X=x)

### Exercise 5

On average(μμ), how many would you expect to be business majors?

6.26

#### Definition of a lens

##### Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

##### What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

##### Who can create a lens?

Any individual member, a community, or a respected organization.

##### What are tags?

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
