題目不是太難。

Question 1

37.6°C (corr. to 1 d.p.)
the maximum absolute error = 0.1°C / 2 = 0.05°C
upper limit = 37.6°C + 0.05°C = 37.65°C
lower limit = 37.6°C - 0.05°C = 37.55°C

Question 2

1700 cm (corr. to 2 sig . fig)
the maximum absolute error = 100 cm / 2 = 50 cm
upper limit = 1700 cm + 50 cm = 1750 cm
lower limit = 1700 cm - 50 cm = 1650 cm

Question 3

83.41 ml (corr.to 4 sig.fig.)
the maximum absolute error = 0.01 ml / 2 = 0.005 ml
upper limit = 83.41 ml + 0.005 ml = 83.415 ml
lower limit = 83.41 ml - 0.005 ml = 83.405 ml
