Final answer:
This question pertains to true statements about percents, which are part of high school level Mathematics, involving the calculation of percents, equivalent fractions, confidence intervals, and probabilities.
Step-by-step explanation:
The question involves the creation of true statements about percents, which aligns with the field of Mathematics, specifically within the study of statistics and probability. The task for the students would involve understanding how to calculate percents, interpret data, and use percentages to express quantities relative to a whole. For example, the statement 'The percent of positive students is about 24%' can be thought of as 24 out of every 100 students. Furthermore, the understanding of equivalent fractions and cross-multiplication is essential in converting between fractions and percentages. Another mathematical concept involved is the understanding of confidence intervals, such as when stating 'We are 95 percent confident that the true proportion...' Establishing confidence intervals involves probability and statistics, and typically occurs in the context of college-level courses. The students must also be able to work with simple probability scenarios, such as calculating the probability of randomly guessing answers on a quiz. These topics are typically covered around the high school level.
