Statistics`NormalDistribution` doesn't work?

I'm not a Mathematica newbie but I thought I was going mad until I noticed
that even this copy from the helpbrowser doesn't get any results:

In[123]:=    << Graphics`Graphics`
In[124]:=    << Statistics`NormalDistribution`
In[125]:=    ndist = NormalDistribution[0, 1]
Out[125]=    NormalDistribution[0, 1]
In[126]:=    pdf = PDF[ndist, x]
Out[126]=    PDF[NormalDistribution[0, 1], x]
In[127]:=    Plot[pdf, {x, -3, 3}]

Plot::plnr: pdf is not a machine-size real number at x = -2.99999975`.
etc.

Any help for this seemingly simple problem would be appreciated!
