Answer:

Student 1.

Step-by-step explanation:

To find the percent error, we subtract the estimated weight and the actual weight, take the absolute value (to eliminate negatives) and divide by the actual weight.

For student 1, this is

|20-15.6|/15.6 = |4.4|/15.6 = 4.4/15.6 = 0.282

For student 2, this is

|15-14.3|/14.3 = |0.7|/14.3 = 0.7/14.3 = 0.049

For student 3, this is

|10-12.7|/12.7 = |-2.7|/12.7 = 2.7/12.7 = 0.213

For student 4, this is

|25-21.4|/21.4 = |3.6|/21.4 = 3.6/21.4 = 0.168

The largest of these is 0.282; this is student 1.
