Answer 1

Given numbers are 31, 35, 27, 29, 32, 43, 37, 41, 34, 28, 36, 44, 45, 42, 30 Arranging increasing order 27, 28, 29, 30, 31, 32, 34, 35, 36, 37, 41, 42, 43, 44, 45 n =15 (odd) If the weight 44 kg is replaced by 46 kg and 27 kg is replaced by 25 kg Then, new values in order be 25, 28, 29, 30, 31, 32, 34, 35, 36, 37, 41, 42, 43, 45, 46 n =15
