This module provides further practice and exercises on Hypergeometric Distribution in statistics
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
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.
On average(μ), how many would you expect to be business majors?
6.26
