Answer #1

First of all it is asking for 'population proportion' so it cannot be number of high school graduates because those are actual numbers not proportion.

Next, UH students does not reflect a good estimate of true population for Honolulu

Hence, Option C) The fraction of high school graduates among a random sample of Honolulu residents

is an unbiased estimate for the population proportion of high school graduates in Honolulu.
