Suppose the mean reaction time to a particular stimulus has been estimated in several previous studies, and it appears to be approximately normally distributed with mean 0.35 seconds with standard deviation 0.1 seconds. On the basis of 10 new observations, the mean reaction time is estimated to be 0.45 seconds with an estimated standard deviation of 0.15 seconds. Based on the sample information, what is the maximum likelihood estimator for the true mean reaction time? What is the Bayes’ estimate of the mean reaction time?
