  1. Is there a difference in the level of pain relief among patients with rib fractures who use painkilling drugs and those who use transcutaneous nerve stimulation (TENS)? A small study that involved 30 people with rib fractures was conducted in an orthopedic office. Usable data were collected from 23 of the patients. The outcome variable of interest is “level of pain: as rated by the patient on a scale from 0-20, where 0 is no pain relief and 20 is complete pain relief. The data:

  A nursing student is studying how long it takes patients to receive pain relief from minor to moderate headache from two different pain relievers. Subjects are randomly and independently assigned to two groups where one is giving the leading product and the other given a new drug about to be released.

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:...
