Question

Estimate the absolute standard deviation (or uncertainty) for the results of the following calculations. Round each result so that it contains only significant digits. The numbers in parentheses are absolute standard deviations. Show your solution and express the final answer and its corresponding uncertainty.

a) y= 2.998(±0.002) - 3.98 (±0.15) + 9.035 (±0.002) = 8.0531

b) y= 39.2(±0.3) x 3.054 (±0.022) x 10^ -2 = 1.197

c) y= [198(±6) - 89 (±3)] / 1335 (±2) + 64 (±7)] = 7.791 x 10^-2
