Question

Explain the difference between an interval estimator and a point estimator for mu. Choose the correct answer below. A. A single number calculated from the sample that estimates a target population parameter is called an interval estimator. A point estimator is a range of numbers that contain the target parameter with a high degree of confidence. B. A single number calculated from a population that estimates a target sample parameter is called a point estimator. An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence. C. A single number calculated from the population that estimates a data value of the sample is called a point estimator. An interval estimator is a set of numbers estimating the range of a data set with a high degree of confidence. D. A single number calculated from the sample that estimates a target population parameter is called a point estimator. An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence.

Answer 1

Answer: D. A single number calculated from the sample that estimates a target population parameter is called a point estimator.

An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence.

Explanation:

When we evaluate an range of values for an unknown population parameter, then it is known as interval estimation .

A single number evaluated from the SAMPLE that estimates an unknown population parameter is known as a point estimator.

The general difference between point and interval estimator is the point estimator is a single value of target parameter while interval estimator is a range of numbers to estimate the values about the unknown population.
