Use this information to answer questions #30 - #35: A set of n = 15 pairs of scores (X and Y values) has SSx = 4, SSy = 25, and SP = 6. 30. What is the Pearson correlation (r) for these data? (SHOW YOUR WORK) 31. How many degrees of freedom (df) do you have? 32. For a two-tailed test with alpha = .05, what is the critical r? %3D 33. What is your decision regarding the null hypothesis? Reject or Fail to Reject 34. For the same data set above, if we set our alpha = .01, find the critical r from the table: %3D 35. With alpha = .01 (as in Question #34 above), now what is your decision regarding the null hypothesis? Reject or Fail to Reject
