Answer:
2291.3
Step-by-step explanation:
The given regression equation is
y=9.82 x + 671
Where y= Hiker's elevation in feet and x= number of minutes.
Here, number of minutes is an independent variable while Hiker's elevation in feet is the dependent variable. The slope coefficient 9.82 depicts that due to unit increase in number of minutes the Hiker's elevation in feet increases by 9.82 feet.
We have to estimate the hiker's elevation after 165 minutes using the above regression equation. We simply put x=165 to estimate the hiker's elevation.
y= 9.82(165) + 671
y= 1620.3+671
y= 2291.3
So, the estimated hiker's elevation after 165 minutes is 2291.3 feet.
