Tollowing statements are true matched pairs)? cerning the mean of the ences between two dependent samples Select all that apply. A. If one has more than 15 matched pairs of sample data, one can consider the sample to be large and there is no need to check for normality. B. The methods used to evaluate the mean of the differences between two dependent variables apply if one has 89 IQ scores of men from Ohio and 89 IQ scores of men from Texas. C. If one has ten matched pairs of sample data, there is a loose requirement that the ten differences appear to be from a normally distributed population. D. If one wants to use a confidence interval to test the claim that μ> 0 with a 0.05 significance level, the confidence interval should have a confidence level of 90%. E. The requirement of a simple random sample is satisfied if we have independent pairs of convenience sampling data.
