    3 suggestions:
1.)    Try executing ?NormalDistribution, and Context[NormalDistribution],
to see if the package loaded correctly.
2.)    Instead of using Statistics`ContinuousDistributions`, try
Statistics`NormalDistribution`.  I know the book makes no distinction
between the NormalDistribution[] contained in these, but my Mathematica
4.0.2 executes your command without error in my running notebook in which I
loaded the latter package, although I have not tested it your way.
2.)    Try 50. instead of 50 -- since your error has something to do with
numerical type.
