Problem 2 in Chapter 11 described a pilot study of the relation between psychotherapists' degree of empathy and their patients' satisfaction with therapy. Four patient€“therapist pairs were studied. The results are presented here, including the means.

(a) Determine the linear prediction rule for predicting satisfaction from empathy.
(b) Draw the regression line. Use the linear prediction rule to figure the predicted satisfaction of patients whose therapist had the following amount of empathy:
(c) 50.
(d) 64.
(e) 80.
(f) Determine the standardized regression coefficient.
(g) Explain what you have done in all the previous parts of this question to someone who understands the mean and deviation scores but does not know any more about statistics.
(h) Find the proportionate reduction in error (using SSError and SSTotal).
