hope this helps :)
 
        
             
        
        
        
Answer:
The  width is  
Step-by-step explanation:
From the question we are told that 
    The population standard deviation is  
     The  sample size is  
     The sample mean  is  
Given that the confidence level is  99% then the level of significance is mathematically represented as  
                
=>            
=>             
Next we obtain the critical value of   from the normal distribution table, the value is
 from the normal distribution table, the value is 
              
Generally margin of error is mathematically represented as 
              
substituting values 
               
               
                
The width of the 99% confidence interval is mathematically evaluated as 
          
substituting values
