Formula Calculation while result recording

Question

While result recording for any Characteristic, the system should calculate some formula to accept or Reject the characteristic.
Eg. Let me take the characteristic as Carbon.
Upper limit     0.100     
Lower limit     0.000
My sample size is 3
While result recording I entered the value as
1  0.055          
2  0.059          
3  0.062
System should calculate the below formulas & the values are in between the tolerance then that should accept or reject the characteristic
X+ H*R
X-H*R
Where
X  - Mean value of the Sample
R – Range (Minimum – Maximum)
H- this is the Standard value given by the customer and it should calculate according to following sample size n
Here Same please size is 3 So the value of H is 1.300 
Samle(n)     (h)          
2     6.360     
3     1.300     
4     0.720     
5     0.510     
6     0.400     
7     0.330     
Now the X+ H*R = 0.068
& X-H*R  = 0.050
So the values are between the tolerance limits. So the system should propose to accept the characteristic Carbon
