can anyone help with question 28 from the CFAI mock exam morning session?
the question gives 2 sample sets of 5 numbers each which are drawn from normally distributed populations with unknown variances. The question than asks what the t statistic to test the hypothesis that the mean difference is equal to 0 is.
i guessed on this one, and the answer key is just all greek symbols with no explanation.
if anyone can explain in laymans terms that would be greta.
thanks
