ttest age == 56

One-sample t test
------------------------------------------------------------------------------
Variable | Obs Mean Std. Err. Std. Dev. [95% Conf. Interval]
---------+--------------------------------------------------------------------
age | 2,857 49.15576 .3310101 17.69279 48.50671 49.8048
------------------------------------------------------------------------------
mean = mean(age) t = -20.6768
Ho: mean = 56 degrees of freedom = 2856

Ha: mean < 56 Ha: mean != 56 Ha: mean > 56
Pr(T < t) = 0.0000 Pr(|T| > |t|) = 0.0000 Pr(T > t) = 1.0000

State the null hypothesis, would you reject or accept the null hypothesis and why?
