Answer:
The sample size
Explanation:
Dr. Prometheus wants to describe the attitudes of all 18-year-old Houstonians concerning the legalization of marijuana. She randomly picks 500 people of that age to fill out her survey. In this study, the population being measured is the sample size. The sample size of a study is the number (n) of observations taken from a population through which statistical inferences for the whole population are made or the number of respondents whose data regarding the study is the basis for the research conclusion.
The population being studied by Dr. Prometheus in the case is known as sample size.
The sample size represents the total population by collecting a number of participants out of it to get knowledge of the total population by observing the sample size. Thus, the sample size must be large enough to get true information about the population.
Hence, the collection of 500 people randomly is a type of sample collection for developing the data for assessment of the survey questions to get the final conclusion.
