Question

A confidence interval for a population mean __________. A. Estimates a likely interval for a population mean B. Estimates likelihood or probability C. Estimates the population standard deviation D. Estimates the population range

Answer 1

Answer:

Option A)  Estimates a likely interval for a population mean is correct

Hence a confidence interval for a population mean is used to  Estimates a likely interval for a population mean

Step-by-step explanation:

Given that a confidence interval for a population mean  Estimates a likely interval for a population mean

For :

A confidence interval is a range of values that’s likely to include a population value with a certain degree of confidence.

It can be expressed as a the (percentage value) $\%$ where by a population mean lies between an upper and lower interval.

Therefore a confidence interval for a population mean is used to  Estimates a likely interval for a population mean

Option A)  Estimates a likely interval for a population mean is correct

Hence a confidence interval for a population mean is used to  Estimates a likely interval for a population mean
