Answer #1


The 10% condition states that sample sizes should be no more than 10% of the population.Whenever there are 10412 students in our population, our sample size should be no more than 10% of 10412 which is equal to 1041

our sample size should be less than 1041. Therefore option c is not correct. Our sample size should be an integer. Therfore option d is not correct. In order to be 95% confident and margin of error to be 3% the sample size should come around 600 .

Therefore, the correct option is C
