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 No, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 3 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 = 3 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. O 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 a = 0.05. O Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 18 and a = 0.05. O 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 a = 0.05. O No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 18 and a = 0.05. O No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 30 and a = 0.05. O No, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 18 and a = 0.05. O Yes, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of n = 18 and a = 0.05. (c) Is it true that in order to be significant, a p value must be larger than 0.90? larger than 0.70? larger than 0.50? What does sample size have to do with the significance of p? Explain your ans O Yes, a larger correlation coefficient of 0.90 means that the data will be significant. O No, a larger sample size means that a smaller absolute value of the correlation coefficient might be significant. O Yes, a larger correlation coefficient of 0.50 means that the data will be significant. O No, sample size has no bearing on whether or not the correlation coefficient might be significant. O Yes, a larger correlation coefficient of 0.70 means that the data will be significant.
