Answer using R studio software

Ex. 3.7 Assume y,~ N(Bo + x3,0), i = 1,2,..., N, and the parameters 3, are each distributed as N(0, 72), independently of one another. Assuming 2 and 72 are known, show that the (minus) log-posterior density of 3 is proportional to 1 (Ji-Bo-jijj) + A-133 where A = 0/7. j=1
