Medical patients who are in physical pain are often asked to communicate their
level of pain on a scale of 0 to 10 where 0 means no pain and 10 means worst
pain. (Note: Sometimes a visual device with pain faces is used to accommodate
the reporting of the

From the distribution above, what is the probability of obtaining a Diff value of -1 or less?

With regard to this distribution, would you consider a Diff value of -0.4 to be statistically significant? Explain.

With regard to how Diff is calculated, if Group A represented a group of patients in your experiment who received a new pain relief treatment and Group B received a pill with no medicine (called a placebo), how would you interpret a Diff value of -1.4 pain scale units in context?

Given the distribution above, if you obtained a Diff value such as -1.4 from your experiment, would you consider that to be significant evidence of the new treatment being effective on average in relieving pain? Explain.
