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

Student learning outcomes

  • The student will analyze 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

In words, define the Random Variable X .

X ~

H(16,7,9)

What values does X take on?

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

Construct the probability distribution function ( PDF ) for X .

x P(x)

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

6.26
