Answer 1

Answer:

(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)
