Hi, 
variable X with a normal distribution with mean 36 inches and standard deviation 2 inches       
finding the X value approximating the 50th percentile of this distribution
*Note: {{{z = blue(x - mu)/blue(sigma)}}}
 NORMSINV(0.50)= 0    | area illustrated to the left of center - the mean value
   z= (X - 36)/2 = 0   
       X = 36, the mean value
