Required information The lengths of two components will be measured several times. The uncertainty in each measurement of the length of the first component is 0₁ = 0.04 cm, and the uncertainty in each measurement of the length of the second component is σ2 = 0.09 cm. Let X denote the average of the measurements of the first component, and let Y denote the average of the measurements of the second component. The total length of the two components will be estimated with the quantity X + Y. Find the uncertainty in the total length if the first component is measured 4 times and the second component is measured 12 times. The uncertainty in X + Y is cm.

Required information
The lengths of two components will be measured several times. The uncertainty in each measurement of the length of the
first component is 0₁ = 0.04 cm, and the uncertainty in each measurement of the length of the second component is σ2 =
0.09 cm. Let X denote the average of the measurements of the first component, and let y denote the average of the
measurements of the second component. The total length of the two components will be estimated with the quantity
X + Y.
Find the uncertainty in the total length if the first component is measured 4 times and the second component is measured 12 times.
The uncertainty in X + Y is
cm.
