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

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?

An important statistical measurement in service facilities (such
as restaurants and banks) is the variability in service times. As
an experiment, two bank tellers were observed, and the service
times for each of 100 customers were recorded. Do these data allow
us to infer at the 5% significance level that the variance in
service times differs between the two tellers? Estimate with 95%
confidence the ratio of variances of the two bank tellers. Teller 1
