Answer:
1. Parameter because the value is a numerical measurement describing a characteristic of a population
Step-by-step explanation:
A parameter is a fixed measure which <u>describes the whole population</u> while a statistic is a <u>characteristic of a sample</u> (which is a portion of the target population).
In a study of all 1963 employees at a college, it is found that "40%" own a computer.
