An experimental surgical procedure is being studied as an
alternative to the old method. Both methods are considered safe.
Five surgeons perform the operation on two patients matched by age,
sex, and other relevant factors, with the results shown. The time
to complete the surgery (in minutes) is recorded.

To test the effect of a physical fitness course on one's
physical ability, the number of sit-ups that a person could do in
one minute, both before and after the course, was recorded. Ten
individuals are randomly selected to participate in the course. The
results are displayed in the following table. Using this data, find
the 95% confidence interval for the true difference in the number
of sit-ups each person can do before and after the course. Assume
that the...
