Question: Directions: Read each hypothesis and reported data and answer the questions below.

Hypothesis two: After treatment, the group receiving a towel bath will have lower anxiety scores that patients receiving a conventional bed bath.

Reported data: Two sample t-tests were used on the state anxiety scores and palmer sweat scores to test the hypothesis. Prior to the bath, there was no significant differences between the two groups on either state anxiety scores or palmer sweat scores. Immediately after the bath procedure, a significant difference in groups means was observed for the state anxiety scores (t=2.04, p=.045) with the lower scores for patients receiving towel bath. There was no significant differences one hour following the bath. At no time were there significant differences in palmer sweat scores. The researchers concluded that towel baths do result in lower anxiety scores.

c) What level of probability was found to exist between the two sets of data?
