1. Two students measured the height of a building whose actual height is 26.5 meters. Laura reported the height as 27.5 meters, while Carlo reported the height as 26.375 meters. (1.1) Which student reported the height more accurately? Explain how you can tell from the numbers. Explanation: Carlos reported the height as 26.375 meters more accurately because accuracy is the degree of closeness between measurement and its true value, which than 26.375 is closer to the actual height is 26.5 (1.2) Which student reported the height more precisely? Explain how you can tell from the numbers. Explanation: Laura reported her height as 27.5 meters since precision refers to the proximity of two or more measurements to each other and 27.5 and 26.5 are both close to one decimal place. so laura is more precisely than carlos. (1.3) Find the absolute error of Laura's guess. (1.4) Find the relative error of Carlo's guess. Answer: Answer:
