I have a sentence:
Comparatively large group of people (13%) choose public transport when commuting to school or attending Holy Mass and the same number choose it when they go shopping.
I am not sure which form to choose - "the same number choose" or "the same number chooses". The number refers to the people, but I don't know: if the word "number" refers to a group of people, but the word "people" is not mentioned after the "number", is plural of the verb correct? Could someone of you tell me which form should I choose?
