Answer:
We are meant to round down fractions of persons to the nearest whole number possible
Explanation:
Here we have the question with regards the result of a fraction of a person to a solution of a statistic question.
Where the result is a fraction, the format is, since most solutions to questions in statistics with regards to people pertain to the maximum amount of persons that fit a class, and since it is not technically feasible to account for the next half of the person after getting your result, we have to put down only the number of whole people possible which means as a rule we always round down the decimal or fractions to the nearest whole number of person
Therefore, you are correct, only that we can put 2 instead of 2.5 as your answer.
