My study group and I are confused about the relationship between the
student t distribution and what we create in part 1. In particular,
what values of nu and s^2 should make our distribution look like a
t-distribution of n-degrees of freedom?

Hi all,
A little over 30 degrees of freedom, and a unit sample variance will do: a
t-distribution with these parameters will be a good proxy for the true Gaussian
distribution.

Hi,
what values of nu and s^2 should make our
distribution look like a
t-distribution of n-degrees of freedom?
Large nu, say 100, and s^2=1 do,
though I don't know why.
Hope it helps.
