Variable | Obs Mean Std. Err. Std. Dev. [95% Conf. Interval]
---------+--------------------------------------------------------------------
alctry | 16,149 991.0647 .0066429 .8441679 991.0517 991.0777
------------------------------------------------------------------------------
mean = mean(alctry) t = 1.1e+05
Ho: mean = 292.0672 degrees of freedom = 16148
Ha: mean < 292.0672 Ha: mean != 292.0672 Ha: mean > 292.0672
Pr(T < t) = 1.0000 Pr(|T| > |t|) = 0.0000 Pr(T > t) = 0.0000
