Correct answer: B (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice B is correct. In the given scatterplot, the x-values represent the distance °F above sea level, in feet, and the y-values represent the temperature, in . The 4,000 point on the line of best fit with an x-value of has a corresponding y-value 35 4,000 of . Therefore, at a distance of feet above sea level, the temperature 35°F predicted by the line of best fit is . °F Choice A is incorrect. This is the temperature, in , predicted by the line of best fit at a distance of 0 feet above sea level. Choice C is incorrect. This is the measured °F 6,000 temperature, in , at a distance of feet above sea level. Choice D is incorrect and may result from conceptual or calculation errors.
