In a regression analysis, a nurse researcher found a correlation of .82 between pain relief scores and satisfaction with nursing care.  She also calculated the following for her regression analysis:

            Pain Relief (x):            Mean = 58       sd = 3.9

            Satisfaction (y):           Mean = 42       sd = 4.4

            slope =                         1.56

            y intercept =                - 3.53

1.  What will be the predicted satisfaction score (expressed as a point estimate) for a patient with a pain relief score of 62?

2. What is the standard error of estimate when predicting satisfaction from knowledge of pain relief score?

3. What would be the interval estimate for satisfaction for the patient in problem 16?
