Answer

We know that the percentile point data provides us information about the data set and their position or rank in the entire data set.

Suppose, if a data value has percentile point data of 75, then this means that 75% of all the values are below the given data value in the entire data set

So, we can use the percentile point data in order to check the position of student A in comparison with student B and C, this will helps us know whether the student A is making a false statement or true statement.
