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>

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² + 2x - 3
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = 3(3)² + 2(3) - 3
- Exponents: f(3) = 3(9) + 2(3) - 3
- Multiply: f(3) = 27 + 6 - 3
- Add: f(3) = 33 - 3
- Subtract: f(3) = 30
The correct answer is the first option
