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
1 is the least prime number
