What is students-t distribution [and why weren't we taught it in
class!]? How does it take into account the uncertainty of the
uncertainty? Does it take into account the uncertainty of that
uncertainty? How would you modify it to do so! As an aside, my
instructor says my error bars represent roughly [how ROUGH...] 2/3
"confidence level" of the true value (what ever that is). If you read
the error bars in my notebook as 90%, it would be misreading them.
And yet you specify 90% of something, what happens if I change it to
90.0000001%?
