1. The problem statement, all variables and given/known data Weight of the plums of a large lot is averaging 70 g and SD 0.85 g. X= the average weight of plums in a pack of 14 plums. Find the variance of the variable X. 2. Relevant equations 3. The attempt at a solution n=14 Average_Total= 70*14=980 SD2 = Variance_Total= 0.852 *12 = 10.115 Variance/n = 10.115/14 =0.7225 Does that make sense so far? I am pretty much stuck here.
