Can anyone verify this please?
The breaking strength of a type of cloth is to be measured for 20 specimen. The underlying distribution is normal with unknown mean but with a standard deviation of 3. Suppose that the unknown mean has a prior distribution that is normal with mean 200 and standard deviation 2. If the average breaking strength for this sample of 20 specimen is 182, determine the Bayes estimate of and an interval around this value that contains with probability .95.
Is this correct?
How do I determine the Bayes estimate of ?
