Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
Given that,
We have to find are we extrapolating or interpolating when we use a least-squares line to forecast y values for x values outside the range of x values seen in the data.
Option A) We are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
<h3>What is extrapolation?</h3>
Extrapolation is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable.
Therefore, Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
