<h3><u>The unknown number is equal to 4.</u></h3>
8x - 27 = 5
Add 27 to both sides.
8x = 32
Divide both sides by 8
x = 4

Answer:
 The correct option is  C
Step-by-step explanation:
From the question we are told that 
      The number of independent variables is  
      The number of observation is  
      
Since n is are independent variables then their degree of freedom is  3 
    The  denominator(i.e z) degrees of freedom is evaluated as 
             
           
           
So for the numerator (n) the degree of freedom is  Df(n) = 3
So for the denominator(i.e z) the degree of freedom is  Df(z) = 43
