statistics question

2-1: Your organization collects data on individual patients shown in Appendix Table 2.  Identify whether each variable is measured nominally, ordinally, or as an interval/ratio variable. (14 points)

2-2:  What statistical measures would you use to summarize the variable for age?  What about for gender?  For convenience satisfaction?  How would you present these graphically? (8 points)

2-3:  If you are interested in whether satisfaction scoring differed by the amount the individual paid is a co-pay, how would you state this inquiry as testable hypothesis (the null and alternative)?  What statistical test would you run to test this hypothesis? (8 points)
