Answer: D. The population is the total number of people who go to the movie theater, and the sample is the first 50 people at the theater.
Step-by-step explanation: The population refers to the entire group or set of individuals that the survey is trying to represent. In this case, the population is the total number of people who go to the movie theater.
On the other hand, the sample is a subset of the population that is selected to gather information and make inferences about the larger population. In this situation, the sample consists of the first 50 people who entered the theater and were asked about their favorite type of movie.
It is important to note that the sample, in this case, is not representative of the entire population of people who go to the movie theater or the entire population of the town of Wayside. The survey only includes the opinions of the first 50 individuals, which may not accurately represent the preferences of the entire population.
