Question: You have developed an educational package which you believe reduces the spouse’s anxiety during childbirth. After establishing and following all the proper protocols, you test your educational package against the standard educational package given to spouses at your hospital. You use an anxiety score where lower scores represent less anxiety. Here are your data:

Standard Package Your Package

34.8 49.4

48.5 48.2

45.1 61.9

33.9 52.0

53.0 39.1

22.4 45.3

45.5 49.5

38.8 46.0

Do a complete hypothesis test (nondirectional with an alpha level of .05) to determine if there is a significant difference. Assume random assignment and equal variances.
