Estimating the mean weight of a small mammal


This diagram shows the theoretical distribution of the estimation error when sampling from a normal population with known standard deviation, σ.

error  =  − μ

error  ~  normal (0,  )

Explain that:

This is a simulation so the data are not real. However they are supposed to be weights of a small mammal and are normal (1000 gm, 200 gm).
