12) As we have noted in previous chapters, even a very small effect can be significant if the sample is large enough. Suppose, for example, that a researcher obtains a correlation of r = .600 for a sample of n = 10 participants. a) Is this sample sufficient to conclude that a significant correlation exists in the population? Use a two-tailed test with a = .05. b) If the sample had n = 25 participants, is the correlation significant? Again, use a two- tailed test with a = .05.
