Can you tell me how to check the levels? what is level?
If you don't know what a level is, how can you even consider doing a T-test? That's what a t-test does, it compares the means of two different levels (conditions, settings, etc.) of a variable (in this case WEIGHT_STATUS) in your data.
You can check the levels in any number of ways; by doing a PROC PRINT or a PROC FREQ on the variable WEIGHT_STATUS. It is also a very good idea to learn how to view your data to debug problems by viewing your data using the viewtable feature in SAS.
