Mark wanted to know the preference of the people in his neighborhood regarding to the candidates running for election. He conducted a survey of two randomly selected samples of people in his neighborhood and recorded the results in the table below.


Which statement is true?

A. Mark will get different estimates for the preferences of all the people in the neighborhood based on the calculations from each sample. This is expected because a small variation can be expected in different random samples.
B. Mark will get different estimates for the preferences of all the people in the neighborhood based on the calculations from each sample. This is not expected because the results of the survey should be the same since the sample sizes are the same.
C. Mark will get the same estimate for the preferences of all the people in the neighborhood based on the calculations from each sample. This is expected because a small variation in the sample will not lead to a variation in the estimation of the population.
D. Mark will get the same estimate for the preferences of all the people in the neighborhood based on the calculations from each sample. This is not expected because a small variation in the sample should lead to a variation in the estimation of the population.
