Dear all,
Running this ttesti, I have got the results below. Does this mean that I
accept the hypothesis that he mean would be 423?
What exactly means each of the three Pr(T?t) seen below, please?
ttesti 12 367 32 423
One-sample t test
------------------------------------------------------------------------
------
| Obs Mean Std. Err. Std. Dev. [95% Conf.
Interval]
---------+--------------------------------------------------------------
------
x | 12 367 9.237604 32 346.6682
387.3318
------------------------------------------------------------------------
------
mean = mean(x) t =
-6.0622
Ho: mean = 423 degrees of freedom =
11
Ha: mean < 423 Ha: mean != 423 Ha: mean >
423
Pr(T < t) = 0.0000 Pr(|T| > |t|) = 0.0001 Pr(T > t) =
1.0000
Thanks, Panos
