Consider the following study: A new health-threatening virus, SHV, has been identified and a research group at the Northern Virginia University (NVU) is developing the vaccine. The scientists at NVU are testing the following hypothesis: people who receive the SHV vaccine do not get the virus. In the clinical trials, one group of test subjects is treated with the vaccine, the other group is given the placebo, a shot containing saline solution without a drug. Both groups have the same number of individuals with identical sex ratio, age range, body type, and similar medical history. Upon administering the vaccine, the researchers measure how many individuals get infected with SHV on a monthly basis in a period of one year. The same experiment is conducted concurrently in several other leading institutions across the country. 1-What is the experimental group in this experiment?
