Which of the following is a sample of the population of bookstores on the west coast of the united states? i. all book stores in california ii. randomly selected children's book stores iii. internet book stores a. i only b. ii only c. i and iii d. iii only e. i and ii

Eliminate (I) "all bookstores in California," because we're choosing a SAMPLE, not an entire population of stores.

Keeping this in mind, we'd not choose "Internet bookstores" unless it's clear that we're sampling these stores, not looking at all of them.

This leaves only "randomly selected children's bookstores."  Even now I'm not comfortable, because this choice focuses specifically on children's stores (instead of on bookstores in general).

Iwish i knew the answer but i don’t but someone will come and us
