Feedback practice problems

Read the feedback class notes.
An amplifier used in a feedback system has a open-loop gain than is known be exactly A = 2000. (There is no variance in amplifier gain.) The system uses a feedback network with nominal factor of β = 1. In a batch of feedback circuits, variance of the feedback factor is ±10%. If we build 10000 versions of the closed-loop circuits using the perfect amps and the imperfect feedback networks, what are the minimum and maximum values for closed-loop gains that we would expect to see?
Note: This scenario of a "perfect" amp and imperfect feedback factor is not seen in "real life", but we can imagine it happening for the purposes of a practice problem.
