When you open SAS, you'll have access to a few permanent libraries such as the sashelp library. You don't need to run a LIBNAME statement or do anything else to gain access to the data in this library.

In the sashelp library there is a dataset called fish. Run the following code to sort the data. You should output the sorted dataset to the work library. Add to the OUT $=$ option to do so$.$

PROC SORT DATA $=$ sashelp.fish OUT $=$;

BY Species;

RUN;

Now run the following code, referencing the outputted dataset from above in the DATA $=$ option:

PROC PRINT DATA $=$ ;

RUN;

What is the height of the $1$st observation listed?
