Question

(a) Is a sample correlation coefficient ? = 0.84 significant at the ? = 0.01 level based on a sample size of n = 6 data pairs? What about n = 12 data pairs? (Select all that apply.) No, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 6 and ? = 0.01. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 6 and ? = 0.01. Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 6 and ? = 0.01. Yes, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 6 and ? = 0.01. No, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 12 and ? = 0.01. Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 12 and ? = 0.01. Yes, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 12 and ? = 0.01. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 12 and ? = 0.01. (b) Is a sample correlation coefficient ? = 0.43 significant at the ? = 0.05 level based on a sample size of n = 15 data pairs? What about n = 28 data pairs? (Select all that apply.) 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 = 28 and ? = 0.05. Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 28 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.
