   I want to know how many individuals in the United States currently take some type of blood pressure medication. I decided to survey 25 people at my local gym to see if they are taking any of these medications. Which of the following statements will be probably be accurate about this situation?

   		I have collected a good, reliable sample
   		My sample is not likely to be representative because it is not big enough
   		My sample is biased because I have restricted who can participate
   		My sample is not likely to be representative because gym-goers are likely in good health

Answer 1

A sample is a representation of population which explains the population completely.

Since here you have taken a sample which are gym goers and also a very small sample as compared to the US population and they do not represent the population completely therefore the following options will apply:

My sample is not likely to be representative because it is not big enough

My sample is biased because I have restricted who can participate

My sample is not likely to be representative because gym-goers are likely in good health
