A researcher would like to evaluate the effectiveness of a pain-relief patch designed for lower back pain. Prior to testing the patch, each of n = 4 patients rates the current level of back pain on a scale from 1 to 8. After wearing the patch for 90 minutes, a second pain rating is recorded. The data are as follows.

A researcher wants to evaluate the pain relief effectiveness of
a new medication for chronic pain sufferers. Using a pain scale
from 0 to 10 (where 0 = no pain at all, and 10 = the most pain you
can imagine), she compares the pain level for a sample of
n1 = 4 people who received the new medication, with the
pain level for a sample of n2 = 4 people who received a
placebo. The data are as follows:...

In a study designed to test the effectiveness of magnets for
treating back pain, 40 40 patients were given a treatment with
magnets and also a sham treatment without magnets. Pain was
measured using a scale from 0 (no pain) to 100 (extreme pain).
After given the magnet treatments, the 40 patients had pain scores
with a mean of 6.0 and a standard deviation of 2.2. After being
given the sham treatments, the 40 patients had pain scores with a...
