Problem set 2: Use the following data to answer questions 6-10 (30 points):

We take another look at health based on the practice question on Page 408, this time examining the relationship between educational attainment and perceived quality of health care. Data for three groups are presented based on the HINTS2012 data set. Present the five-step model for these data, using alpha = .01. QUALITY CARE is measured on a five-point scale: 1excellent, 2very good, 3good, 4fair, and 5poor. Note how a lower score indicates a higher quality of care. Chapter Exercises #1 and #3 on pages 318-319 are helpful to complete this problem set.
