The correct option regarding the volunteer sampling in this problem is given as follows:
Inferences cannot be made about all blood pressure patients, and the conclusion cannot be made that the new medication lowers blood pressure more effectively than the original medication for patients taking blood pressure medication.
<h3>What is volunteer sampling, and why it should not be used?</h3>
Volunteer sampling is a technique in which each participant in the sample opts to join the research, as is the case for this problem, as each participant opted to join the weight loss project.
The fact that the participants opt to join the research is a drawback of volunteer sampling, as these participants may be predisposed to change their habits, for example, which may cause bias on the result of experiment.
Due to the bias that can be caused by the use of volunteer sampling, inferences cannot be made about the population, and neither conclusions can be made about the outcome of the test.
<h3>Missing Information</h3>
The problem is:
A pharmaceutical company develops a new generation of blood pressure medication that may also help with cholesterol. The research and development department advertises in the local papers and online for volunteers who already take blood pressure medication to participate in a study for the new medication. Two hundred people volunteer, and their current blood pressure along with their cholesterol levels are measured. The first 100 volunteers are assigned to the new generation of blood pressure medication, and the next 100 are assigned to the original medication. At the end of the study, the subjects' blood pressures and cholesterol levels are measured. The group with the new medication is found to have significantly lower overall blood pressure than the original medication group. It was also determined that the new medication did not significantly lower cholesterol levels.
