Problem-Solving and Data Analysis Difficulty: Easy

The scatterplot shows the temperature, $in degrees Fahrenheit (° F)$ , and the distance above sea level, in feet, measured at $6$ locations on Mount Jefferson. A line of best fit is also shown.

At a distance of $4,000$ feet above sea level, what is the temperature, $in ° F$ , predicted by the line of best fit?

Explanation

Choice B is correct. In the given scatterplot, the x-values represent the distance above sea level, in feet, and the y-values represent the temperature, in $° F$ . The point on the line of best fit with an x-value of $4,000$ has a corresponding y-value of $35$ . Therefore, at a distance of $4,000$ feet above sea level, the temperature predicted by the line of best fit is $35 degree upper F$ .

Choice A is incorrect. This is the temperature, in $° F$ , predicted by the line of best fit at a distance of $0$ feet above sea level.

Choice C is incorrect. This is the measured temperature, in $° F$ , at a distance of $6,000$ feet above sea level.

Choice D is incorrect and may result from conceptual or calculation errors.
