If the term σo is very large then on is closer to σ0 b. σ/√n is the standard deviation of the sample mean with an informative prior. c. If the term σ0 is very small then µn is closer to µo . d.σ0 is the standard deviation of the posterior distribution of the mean with informative prior. e.σn is the standard deviation of the posterior distribution of the mean with informative prior
