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: 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.
Step-by-step 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.
First, you have to find how much 7.5% is coming out of 10,000. So in this case it's 750. Multiply 750 by 12 years. Thats 9000, you then subtract 9000 and 10,000 to get 1,000.
