Answer :
Final answer:
The question is related to sampling methods in mathematics, specifically statistics, as it involves using a random number generator to randomly select students for a survey, ensuring unbiased and representative data collection. Thus Option a is Correct.
Explanation:
The statement "Students in an automotive class were selected by their ID number using a random number generator and then asked their preference in brands of tools" can be categorized as a scenario related to sampling methods in statistics, a branch of mathematics. Sampling involves selecting a subset of individuals from a population to estimate characteristics of the whole population.
In the case presented, the use of a random number generator signifies an attempt to carry out random sampling, which is important for obtaining a representative sample of a larger population. In statistics, this technique helps to ensure that every individual has an equal chance of being selected, reducing possible sample bias. Various examples of sampling methods and their implications can be found in exercises that require analyzing social data, conducting opinion polls, and other research activities that involve hypothesis testing and data collection on car preferences among different demographics.
