Hi Gregory,
At least in Mathematica version 5.2, the built-in function MeanTest 
requires TWO parameters, that is the data and the mean. Your "example"
exhibits only a list of numbers. From the online help
"MeanTest[list, mu0, options] returns a probability estimate (p-value) 
and other hypothesis test information for the relationship between the 
hypothesized population mean mu0 and Mean[list]."
