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

Items 16, 17 and 18 relate to the following: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

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

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

Items 19-21: A nurse researcher is investigating the effect of timing of standard pain control interventions on severity of pain in adolescents with sickle-cell disease. She establishes three treatment protocols: 1) initiation of pain control immediately upon the presence of prodromal sign (an “aura” signaling the imminent onset of pain); 2) initiation of pain control one hour after the onset of pain; and 3) initiation of pain control only at the points where non-steroidal anti-inflammatories and guided imagery are no longer effective in keeping pain bearable. She conducted a one-way ANOVA to analyze her data and the following table summarizes her findings:
