A set of length measurements are obtained with the values 165.6 ± 0.3, 165.1± 0.4,166.4± 1.0, and 166.1± 0.8 cm. Find the best estimate of the length and its accuracy.
What would have been the best estimate if the accuracies of the measurements were ignored?

1) A set of 13 measurements are obtained with the values 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,11, 12, each of which is found once. Find the average value of the measurements and thestatistical uncertainty based on the measurements. Consider the function n= 1/Lfor 0≤x≤Land n= 0 otherwise. Find theaverage value of x and its spread. Compare the two results. (Use appropriate integrals instead of the sums you used in the previous problem.)
