Therefore, the range of his true weight is about 62.4kg-67.6kg.
2)
12.5x0.4%
=0.05seconds
Therefore, the range of her true record is about 12.45seconds-12.55seconds

a)
maximum absolute error: 0.05
upper limit:1.05
lower limit: 0.95
b)
maximum absolute error: 0.005
upper limit:1.005
lower limit: 0.995
c)
maximum absolute error: 0.0005
