How to set and check normal distribution on a data set?
It's hard to be sure of anything without having a glimpse at your data but what I assume from what you are saying is:

you have 2 classes which probably are  given as 1 columns

you have 29 features

you have 200 samples
Edit: Then while writing my answer I'm not too sure what you wanna do. If you have 2 classes it is likely that you are about to do some classification tasks so I don't really get what you want to modelize with a normal distribution.
