assume we obtain the following set of measurements of some quantity of interest x: 65, 64, 63, 67, 59, 60, 62, 61, 62, 64 then the best estimate for x (the sample mean) is 62.7, and the sample standard deviation is 2.41. calculate the uncertainty of the best estimate. round your answer to two (2) decimal places for entry into canvas. do not enter units. example: 1.23
