Answer:
B. Parameter
Step-by-step explanation:
When something is taken from a sample and estimated to the entire population, it is a statistic. For example, if you survey 200 Central New York residents, an 60% of them say they are Buffalo Bills fans, the 60% is a statistic.
When something is true to the entire population, it is a parameter. If i study the voting preference of all 53 players on the Buffalo Bills active roster, and 83% are Democrats, the 83% is an parameter.
In this problem, we have that:
Of all DeVry students, a study found that 43% of them are business majors.
The keyword is all, meaning that the 43% is true for the entire population.
So the correct answer is:
B. Parameter
