Suppose that a random sample of size 20 is taken from a normal distribution with unknown mean and known variance equal to 1. The sample mean was found to be ¯x = 10. A normal distribution for the mean was chosen for the prior, and the posterior is N(15, 0.12). What were the prior mean and prior variance?
