1. (Please submit Excel file along with this solution) A study was conducted to investigate the effectiveness of hypnotism in reducing pain. Results for randomly selected subjects are shown in the table. The “before” value is matched to an “after” value. Test the hypothesis that hypnotism reduces pain without using a significance level. Subject A B C D E F G H Before 6.6 6.5 9.0 10.3 11.3 8.1 6.3 11.6 After 6.8 2.4 7.4 8.5 8.1 6.1 3.4 2.0

8. A study was conducted to investigate the effectiveness of
hypnotism in reducing pain. Results for randomly selected subjects
are the following:
Subject A B C D E F G H
Before 6.6 6.5 9.0 10.3 11.3 8.1 6.3 11.6
After 6.8 2.4 7.4 8.5 8.1 6.1 3.4 2.0
The measurements are in centimeters on a pain scale. Higher
values correspond to greater levels of pain. Perform a hypothesis
test to determine if Hypnotism is effective in reducing pain.

A study was conducted to investigate the effectiveness of
hypnotism in reducing pain. Results for randomly selected subjects
are given below. At the 1% level of significance, test the claim
that the sensory measurements are lower after hypnotism (scores are
in cm. on a pain scale). Assume sensory measurements are normally
distributed. Note: You do not need to type these values into
Minitab Express; the data file has been created for you.

A study was conducted to measure the effectiveness of hypnotism
in reducing pain. The measurements are centimeters on a pain scale
before and after hypnosis. Assume that the paired sample data are
simple random samples and that the differences have a distribution
that is approximately normal. Construct a 95% confidence interval
for the mean of the "before−after"differences. Does hypnotism
appear to be effective in reducing pain?
