Answer choice D, A,B, and C both equal 3.
        
                    
             
        
        
        
Answer:
a
The estimate is  
b 
Method B this is because the faulty breaks are less 
Step-by-step explanation:
The number of microchips broken in method A is  
 The number of faulty breaks of method A is  
  The number of microchips broken in method B is  
  The number of faulty breaks of method A is  
   The proportion of the faulty breaks to the total breaks in method A is 
        
       
  The proportion of the faulty to the total breaks in method B is
        
 
      
For this estimation the standard error is  
       
   substituting values 
        
       
The z-values of confidence coefficient of 0.95 from the z-table is  
        
The difference between proportions of improperly broken microchips for the two breaking methods is mathematically represented as
         ![K = [p_1 - p_2 ] \pm z_{0.95} * SE](https://tex.z-dn.net/?f=K%20%3D%20%5Bp_1%20-%20p_2%20%5D%20%5Cpm%20z_%7B0.95%7D%20%2A%20SE)
substituting values 
         ![K = [0.08 - 0.07 ] \pm 1.96 *0.0186](https://tex.z-dn.net/?f=K%20%3D%20%5B0.08%20-%200.07%20%5D%20%5Cpm%201.96%20%2A0.0186)
          
The interval of the difference between proportions of improperly broken microchips for the two breaking methods is

Answer:
The answer is 45.
Step-by-step explanation:
60% of a number is 54, find the original number
54 ÷ 60% 
= 54 ÷ 60/100
= 54 * 100/60
= 90
50% of 90 is 
90 * 50%
= 90 * 50/100
= 90 * 1/2
= 45
