1. What is the focus of the example Figure 7-1 in the section introducing the statistical technique of this exercise?

3. State the null hypothesis for the nursing outcome activity tolerance.

4. Was there a signi?cant difference in activity tolerance from the ?rst home visit (HV1) to the fourth home visit (HV4)? Was the null hypothesis accepted or rejected? Provide a rationale for your answer.

5. In Figure 2 , what nursing outcome had the lowest mean at HV1? Did this outcome improve over the four HVs? Provide a rationale for your answer.

7. State the null hypothesis for the nursing outcome family participation in professional care.

8. Was there a statistically signi?cant difference in family participation in professional care from HV1 to HV4? Was the null hypothesis accepted or rejected? Provide a rationale for your answer.
