Which of the following statements are true concerning the mean of the differences between two dependent samples (matched pairs)? Select all that apply. ... A. The methods used to evaluate the mean of the differences between two dependent variables apply if one has 91 heights of voters from Ohio and 91 heights of voters from New York. B. If one has more than 21 matched pairs of sample data, one can consider the sample to be large and there is no need to check for normality. C. The requirement of a simple random sample is satisfied if we have dependent pairs of voluntary response data. D. If one wants to use a confidence interval to test the claim that Hd >0 with a 0.01 significance level, the confidence interval should have a confidence level of 98%. E. If one has five matched pairs of sample data, there is a loose requirement that the five differences appear to be from a normally distributed population.
