If you mean pixel levels in that range:
school(school > 100 & school < 190) = 40;

school = imread('school.tif');
school(school > 100 & school < 190) = 40;
imshow(school)

Try
school(school >= 100 & school <= 190) = 40;
Same as the others had but since 100 and 190 are in the range I used the = sign whereas the others didn't so pixels with values of 100 and 190 will not get set to 40 in their answers.
