Sentence Correction

Here is a note from the internet resource "What are Verbs.doc"

Some nouns have irregular plural forms without "s" (man > men). To show possession, we usually add 's to the plural form of these nouns:
singular noun plural noun
my child's dog my children's dog
the man's work the men's work
the mouse's cage the mice's cage
a person's clothes people's clothes

can somebody plz confirm that

"my children's dog" "the men's work" "the mice's cage" etc. would be correct on GMAT ?
