converting an excel calculation to DAX

I have a user with a specific request for help converting an Excel spreadsheet into a Power BI report. The data table that he is using is below.

NC Rate Doc = Documentation / Production

3mo Avg is three month rolling average of NC Rate Doc

The Alert is 3mo avg+2*sqrt(3mo avg*(1-3mo avg) / Production)

OR

$E4+2*SQRT($E4*(1-$E4)/$B4)

I was able to find enough information to get the rolling average ( listed below) but the Alert is alluding me

 

Any help is greatly appreciated.

I was able to finally sort things out. I was making things much more difficult than they needed to be. This is the measure that I put together.

 

Alert = 
VAR Result =
    [NCs R03M]+2*SQRT(DIVIDE([NCs R03M]*(1-[NCs R03M]),'Key Measures'[Monthly Orders]))

RETURN
    Result
