Statistics are used to estimate population parameters, particularly when it is impossible or too expensive to poll an entire population. A particular value of a statistic is referred to as a(n) .

Estimate

Step-by-step explanation:

Getting the values of the parameters in a population can be very difficult some times. This might be due to the size of the population in question. Hence, we might be needing to use a specific portion of the population to serve as a representative of the entire population.

Now this portion can give some answers but these answers are just representative of the sample and not the entire population. This is why it is called an estimate of the entire population

the first one, all those points on the line just make a strait line.
