9.3.1 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 requirement of a simple random sample is satisfied if we have matched pairs of convenience sampling data. B. The methods used to evaluate the mean of the differences between two dependent variables apply if one has 41 weights of workers from California and 41 weights of workers from Texas. C. If one has more than 14 matched pairs of sample data, one can consider the sample to be large and there is no need to check for normality. D. If one has twenty matched pairs of sample data, there is a loose requirement that the twenty differences appear to be from a normally distributed population. ☐E. If one wants to use a confidence interval to test the claim that μd>0 with a 0.01 significance level, the confidence interval should have a confidence level of 98%. Question Help
