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.
They are all pretty easy all you do is multiply the cost by the amount of things you buy. For example number 4 your variables are cost (c) and songs (s). Your equation is c•s so $0.99 • s. 50 songs would be .99 • 50 which is $49.50
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
