Everyone knows that giraffes are tall, but how much do they weigh?

Let's suppose that the weight of male giraffes is normally distributed with mean 1200 kg and standard deviation 200 kg. I volunteered at the zoo and was given the task of weighing their male giraffe Beau. Now weighing a giraffe is not easy and the process produces random errors following a N(0, 1002)distribution. To compensate for the inaccuracy of the scale I weighed Beau three times and got the following measurements:1250 kg, 1300 kg, 1350 kg .

What is the posterior expected value of Beau's weight?
