What about n = 12 data pairs? (Select all that apply.) O 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 a = 0.01. O Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 3 and a = 0.01. O Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 12 and a = 0.01. O No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 3 and a = 0.01. O No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 12 and a = 0.01.

O 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 a = 0.01. (b) Is a sample correlation coefficient p = 0.40 significant at the a = 0.05 level based on a sample size of n = 18 data pairs? What about n = 30 data pairs? (Select all that apply.) O Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 30 and a = 0.05.
