What will be the value of the LCL of the x chart of the GCC when the value of x =12, and the value of R̅= 0.1 and sample size = 4?

What will be the value of the LCL of the x chart of the GCC when the value of x =12, and the value of R̅= 0.1 and sample size = 4? Correct Answer 12.0729

We know that, for n=4, A2=0.0729 Putting the above data into the equation of the UCL of the x̅ chart of GCC, we get, UCL=12.0729.
