How to make a certain percentage of values in an existing matrix, between a set range of values. Probably easy but I am a newbie.

So I have these commands in my script to create a 25x10 matrix of randomly assigned values between 50 and 100. However I need to make 10% of those randomly assigned values between 30 and 50, with the ability to change the percentage at will. Any help would be great.

What about this:
my_percentage = 10;
my_piece = prod(size)*my_percentage/100;
sub_score=randi([30,50],[1, my_piece]);
rand_idx = randperm(prod(size),my_piece);
