Say you're measuring the length of a string L. You measure it 6 times and get the following measurements:12.3 cm, 11.8 cm, 12.2 cm, 10.7 cm, 12.8 cm, and 12.1 cm.
(a). What is your average measured length L_average?
(b). What is the random error on this average measured length,
L_average?
(c). Let us say that the "true" length of the string is 10.1cm. Are the above measurements accruate? Are they precise? Explain why.

Length of a rod: Engineers on the Bay Bridge are measuring tower rods to find out if any rods have been corroded from salt water. There are rods on the east and west sides of the bridge span. One engineer plans to measure the length of an eastern rod 25 times and then calculate the average of the 25 measurements to estimate the true length of the eastern rod. A different engineer plans to measure the length of a western...
