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 - 15 and a = 0.05. No, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of 29 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 = 29 and 0.05. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of 29 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.

Answer 1

Solution: We have to compare the critical value with the correlation value. If the critical value is greater than the absolute value of the correlation, the relationship is not significant.

If the critical value is less than the absolute value of the correlation, the relationship is significant.

(a) is a sample correlation coefficient 0.83 significant at the 0.01 level based on a sample size of n data pairs? What about n = 11 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 = 11 and a = 0.01. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 11 and a -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 = 4 and a = 0.01. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 4 and a = 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 4 and a = 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 - 11 and a = 0.01 Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 11 and a = 0.01. Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 4 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 = 15 data pairs? What about n = 29 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 = 29 and a = 0.05. Yes, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 15 and a 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 a = 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 29 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 - 29 and a = 0.05. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n 29 and a 0.05. No, because the absolute value of the given correlation coefficient is smaller than that for a sample size of n = 15 and a 0.05.
