Ten independent observations were made of the time to load a pallet. The observed times, in minutes, were 104, 122, 110, 170, 95, 96, 100, 73, 82, and 113. Compute the sample mean of this data. Solution Sample mean= sum of all observations/ number of observations =(104+122+110+170+95+96+100+73+82+113)/10 =1065/10 =106.5 Sample mean is 106.5.
