Question:

Suppose y1,…, yn are independent from a N(????,????) distribution, and ???? has a N(????0,????0) prior distribution. With ???? known, derive the posterior distribution.

Explain how the posterior mean is a weighted average of the prior mean and the sample mean and the posterior precision is the sum of the prior precision and the data precision. Discuss their behavior as n increases.
