Imagine a population of N = 4 individuals, A, B, C and D. Individuals A and B are planning to vote in favor of a controversial referendum, whereas individuals C and D are planning to vote no. In the foreground of the referendum, you are asked to conduct a poll of n=2 individuals. Considering all conceivable simple random samples without replacement, what is the range in the estimates of the percentage of people who support the referendum?

Best ResponseYou've already chosen the best response.1Suppose your sample is \(\large \{C, D\}\) They gonna say no, so the percentage in favor is \(0\%\)

Best ResponseYou've already chosen the best response.0A,B Say yes, so percent in favor is 100%... but not sure how to apply this to this question!

Best ResponseYou've already chosen the best response.0let us understand the key terms: sample size, n without replacement

Best ResponseYou've already chosen the best response.0Sample size would be the randomized people in the population being considered. You must realize that sometimes a population is too big that it would not be feasible to include them all in the study so instead we select random people that would best represent a whole population, but if it is small, then it is much easier. If we want to do a statistical analysis, for example, of a population that is for gun control and against. Say, there are 4 total voters representing of equal number between Republicans and Democrats. Republicans like their guns and Democrats like to control the ownership. Since our population, n, is so small that we can include them all in our list. They can be grouped accordingly, but at the same time, we can also randomize (assign numbers) them. \(Voters: 1, 2, 3, 4 \) where Republican: 1, 3 Democrat: 2, 4 But in our analysis we only want people that are against the gun control. So, we can immediately tell that we now have a smaller group of people {1, 3}, n = 2. Now here's the other term, WITHOUT REPLACEMENT what this means is that if I randomly selected my first selection out 1 and 3, I cannot put the number back into the selection. Meaning if I picked 3, then there is only 1 left to be picked next. If it says WITH REPLACEMENT, after I picked 3, then I put 3 back into the group to be selected and there's a chance that I might pick it again the next round of selection or not.
