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 constructed a 99% CI, how would it compare with the 95% CI  (A) It should be wider than the 95% CI of Q5. (B) It should be of the same width as the 95% CI of Q5. (C) It should be narrower than the 95% CI of Q5. (D) We cannot tell, because the information is insufficient.
