Suppose that you are interested in the number of people in each household in the U.S. Your sample includes 10 households, with a mean 2.5 and a standard deviation 1.2. If you sampled 100 households, how would it compare from 99% Cl to 95% CI  (A) It should be wider than the 95% CI. (B) It should be of the same width as the 95% CI.  (C) It should be narrower than the 95% CI.  (D) We cannot tell, because the information is insufficient.
