Calculates the inverse of the cumulative NORMDIST normal distribution function.
NORMINV(p, α, λ)
The normal distribution is a family of continuous probability distributions, with two controlling parameters α and λ.
NORMINV returns the value n, such that NORMDIST(n, α, λ, 1) is p.
NORMINV(0.92, 63, 5)
returns approximately 70.
