T-test in Statstics 1

TI'm studying Statistics 1:  Introduction to ANOVA, Regression and Logistic Regression, and I'm trying to do the exercise in Chapter testing whether the new teaching method for German grammar is significantly different than the standard method.  I ran the code to define the Statdata libray successfully.  However, when I run the code for the t-test, the output log says that 'STATDATA.GERMAN.DATA ' does not exist.  I looked into my folder and see that ECST192, where the datasets ought to reside, is empty.  What am I missing here?
