*So, just to introduce you a couple of the Stata functions for the chisquare distribution,
. display chi2tail(1,3.8416)
.04999579
* chi2tail takes (df, statistic) and gives you tail probability
. display invchi2tail(1, .05)
3.8414588
* invchi2tail takes (df, probability), and gives you the statistic. And by the way note that 3.84 is 1.96^2, because chisquare(1) is the square of a standard Normal, or N(0,1) distribution.
. display invchi2tail(1, .05)
3.8414588
. display invchi2tail(1302, .05)
1387.0575
. display chi2tail(7,29)
