Answer 2

A. The population in this scenario refers to the entire group or target population about which the cereal manufacturer seeks information or wants to make inferences. In this case, the population would consist of all children who consume or potentially could consume the cereal products being evaluated.

B. The sample is a subset of the population that is selected for the study. In this case, the sample includes the group of 100 children who were asked to evaluate each brand of cereal and express a preference. These 100 children represent a sample of the larger population of all children.

C. The study described in the scenario is experimental. It involves manipulating the independent variable (the order in which the cereal brands were fed to the children) and observing the resulting dependent variable (the children's preference). By randomly assigning the order of cereal brands, the researchers aim to reduce bias and establish a cause-and-effect relationship between the cereal brand and the preference expressed by the children. Thus, this study is experimental in nature.

To determine the population, sample, and the nature of the study, you need to analyze the details provided in the scenario. It is important to identify the target population, the subset of participants selected for the study, and the nature of the research design (observational or experimental) based on the information given.
