It is irrational.

A = π r^2 = π[3/4 cm]^2 = 9π/16 cm^2

myrzilka [38]

Answer:

The difference between the sample statistic and population parameter is called sampling error.

Step-by-step explanation:

We are given the following in the question:

  • A sample is a part of population, it is a subset of population.
  • A sample statistic describes the sample. It is a characteristic of sample and different from the population.
  • A parameter describes the population. It is characteristic of a population.
  • A sample may not be able to represent the whole population and this may lead to error.
  • Thus, sampling error is the difference between the sample statistic and population parameter.
  • It arises when the sample is not able to describe the population.

The difference between the sample statistic and population parameter is called sampling error.
