Chapter 11.4, Problem 12E

To determine

To find and interpret the marginal frequencies.

Answer to Problem 12E

The marginal frequency of males is 226.

The marginal frequency of females is 228.

The marginal frequency of associate’s degree holders is 120.

The marginal frequency of bachelor’s degree holders is 244.

The marginal frequency of master’s degree holders is 90.

Explanation of Solution

Given information :

The two-way table regarding males and females who hold associate’s, bachelor’s and master’s degree holders.

Two-way tables are frequency tables that depict data of two categories, but are gathered from the same source. The entries in a two table are such that they represent data of the rows as well as the columns.

On analyzing the two-way table, use marginal frequency who are males.

  $58+126+42=226$

On analyzing the two-way table, use marginal frequency who are females.

  $62+118+48=228$

On analyzing the two-way table, use marginal frequency who are associate’s degree holders.

  $58+62=120$

On analyzing the two-way table, use marginal frequency who are bachelor’s degree holders.

  $126+118=244$

On analyzing the two-way table, use marginal frequency who are bachelor’s degree holders.

  $42+48=90$
