Answer:
<h3>Option A) Estimates a likely interval for a population mean is correct</h3><h3>Hence a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u></h3>Step-by-step explanation:
Given that a confidence interval for a population mean <u>Estimates a likely interval for a population mean</u>
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 <u>Estimates a likely interval for a population mean</u>
Option A) Estimates a likely interval for a population mean is correct
<h3>Hence a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u></h3>
