Question

4. (25) Eleven students measure the lifetime of an excited state, with the results given in the table below. 000 1.2 Measurement Lifetime (sec.) Error (sec.) 34.4 1.6 32.2 35.4 1.5 33.5 1.4 34.7 33.5 27.9 32.0 32.4 31.0 19.8 1.9 00 5 Find the best estimate of the true lifetime, and its error.

Answer 1

the best estimate of lifetime is that has a minimum error among all the lifetime error so here 2nd measurement has less error which is 1.2 and estimate is 32.2. which is the best estimate.
