I've been typing this equations but these equations does not get enough line spacing spacing. I get space sufficient if I did type them separately but I want them aligned too.
following is the code:
\begin{align*}
\chi^2 & = \frac{\sigma_{s}^{2}}{\sigma_{p}^{2}} (n-1)\\
& = \frac{31.11}{20} (10-1) \\
& = 13.999
\end{align*}

enumerate
andenumitem
; choose one or the other, but not both. I'd recommend usingenumitem
... And there's no point in loadingmathpazo
if you're going to clobber it later by loadingmathptmx
.
