Many people in the small mid-western town of Hootville are stricken with a disease called, "BUGGO."
Many of those who become ill recover within 7-10 days.
Through intensive study, "BUGGO" is now believed to be cause by the bacterium, "GOTCHA." In
their fight against "BUGGO", a new drug, "X", has been shown to kill the "GOTCHA" bacteria, which was
grown in a test tube. Drug "X" was also tested in dogs and found to cure those stricken with "BUGGO."
Researchers decided to test this new drug on some of the people in Hootville. They hypothesized that
the drug would also kill "GOTCHA" in humans. They deduced that if given drug "X", that the people would
recover from "BUGGO" faster than those who did not receive it.
The researchers prepare 2 kinds of tablets that were identical in every way except that one group of
tablets contained drug "X" and the other group did not. The group that did not contain the drug is called a
placebo.
The researchers selected 2 groups of people who had just gotten the disease. 25 people in group A were
given the tablets containing the drug. 25 people in group B were give the placebo.
In 3 days time, 90% of the people give the drug were well while those given the placebo all took about 9
days to get well.
