Answer: 3
Step-by-step explanation:
Given: A sample of 100 production workers is obtained. The workers are classified by gender (male, female) and by age (under 20, 20−29, 30−39, and 40 or over).
Here,
Total classes as per gender: k = 2 (male female)
Total classes as per age : m = 4 (under 20, 20−29, 30−39, and 40 or over)
Now , the degree of freedom = (k-1) ( m-1)
= (2-1) (4-1)
= (1)(3)
= 3
Hence, there are 3 degree of freedom.
