(a) Suppose n = 6 and the sample correlation coefficient is r = 0.90. Is r significant...
Question:
(b) Suppose n = 10 and the sample correlation coefficient is r = 0.90. Is r signify cant at the 1% level of significance (based on a two-tailed test)?
(c) Explain why the test results of parts (a) and (b) are different even though the sample correlation coefficient r = 0.90 is the same in both parts. Does it appear that sample size plays an important role in determining the significance of a correlation coefficient? Explain.
