Using Bayesian for estimating parameter

Thanks you replied my post.

I will present for you the detail my post. the first I only know the value range of S [0,1]. I carried out random the S value with seed (20). I have the 20 values and then I experiments with this 20 values. I have corresponding 20 values of K. I see the K coefficient have the normal distribution with mean 1.3 and standard deviation = 0.05. Now I want to consider the posterior of the S coefficient. How to consider the posterior of the S coefficient ?
thanks you.
