Total behavior problem scores.
If children who having difficulties in everyday-life because of family matter, their behavior score will be different from ordinary those. Suppose that we know population parameter:

• 
  
• 
  
• We took a sample whose size is
  
• {48, 62, 53, 66, 51}
  
• 
  
• 
  
• Problem. . . . Are they different from the population?
