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.)
