Question

data collected during a particular lab: density of an aluminum cube (g/cm³): student a student b student c trial 1 2.632 1.532 2.132 trial 2 2.725 1.525 1.525 trial 3 2.660 1.562 3.262 ave. 2.672 1.540 2.306 actual density of al = 2.699 g/cm³ student a student b student c

Explanation:

Step1: Calculate absolute - error for Student A

$|2.672 - 2.699|= 0.027$

Step2: Calculate absolute - error for Student B

$|1.540 - 2.699| = 1.159$

Step3: Calculate absolute - error for Student C

$|2.306 - 2.699|= 0.393$

Step4: Compare errors

Since $0.027<0.393 < 1.159$, Student A has the smallest error.

Answer:

Student A
