A movie complex has eight different movie theaters. The manager of the complex wants to conduct a survey to determine which snacks to add to the menu which represents the best sample. The manager could use for the survey.
To get the most representative sample for the survey, the manager should choose a random sample from each of the eight different movie theaters. This will ensure that all types of customers who attend the movie complex are included in the survey, including those who prefer different genres of movies or different screening times. The sample size should also be large enough to yield statistically significant results, so the manager may want to consider surveying at least 100 customers from each theater. Additionally, the survey should ask open-ended questions to allow customers to suggest their preferred snacks, as well as multiple-choice questions to gauge overall preferences.
