Nurse researchers hypothesized that the use of therapeutic touch would reduce anxiety levels in pre-op hip replacement patients. The null hypothesis would be:

a.Therapeutic touch reduces anxiety levels in pre-op hip replacement patients.

b.Therapeutic touch does not reduce anxiety levels in pre-op hip replacement patients.

c.Therapeutic touch reduces 25% of anxiety levels in pre-op hip replacement patients.

D. Some other therapy reduces anxiety levels in pre-op hip replacement patients.
