    (c) 78% is a parameter and 72% is a statistic

    Step-by-step explanation:

    78% of students are receiving financial aid.

    Number of samples selected = 100

    72% of the sample selected are receiving financial aid.

    The population is a made up of all the individuals we want to collect information from (the students of a particular college)

    The part of the population from which sample are taken is called the sample.

    78% describes the entire population while 72% describes the sample (100 students)

    A parameter is a descriptive measure for a population while a statistic is a descriptive measure for a sample. Therefore

    78% is a parameter while 72% is a statistic (C)
