UNIT 8
Estimating the Expectation
A measurement follows the normal distribution with a standard deviation of
15 and an unknown expectation μ. You can consider that measurement to
be the "original" distribution. Two statisticians propose two distinct ways to
estimate the unknown quantity μ with the aid of a sample of size 36. They
will do that by evaluating two different SAMPLING DISTRIBUTIONS to
determine which method is better. There are two statisticians involved in
this task: statistician "A" and statistician "B." Statistician A proposes to use
the sampling distribution of the sample average as an estimate.
Statistician B proposes to use the sampling distribution of the sample
median instead. In order to choose between the two options they agree to
prefer the statistic that has a smaller variance (with respect to the sampling
