Hello hard working sas colleagues!

I have a very simple question. I have tow samples of different sizes
that contain each a character variable with 4 different parameters (m1,
m2, m3, m4). Is there any possibility to check if the percentage of m1
in sample one and sample two are significantly different? If yes how?

I know how to perform a ttest for two samples of different sizes on the
mean on some specific variable. But I have no clue how to deal when what
I want to check is not the mean but the percentage and when this
variable is not numeric but a character variable.

Please help!!!

Many thanks and all the best for the remaining days of the year,
Adelina.
