Question

(b) Is a sample correlation coefficient ? = 0.40 significant at the ? = 0.05 level based on a sample size of n = 15 data pairs? What about n = 30 data pairs? (Select all that apply.) Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 15 and ? = 0.05. Yes, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 30 and ? = 0.05. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 15 and ? = 0.05. No, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 15 and ? = 0.05. Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 30 and ? = 0.05. No, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 30 and ? = 0.05. Yes, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 15 and ? = 0.05. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 30 and ? = 0.05.
