Suppose we want to estimate the mean salary of seven people based on a sample of size 3 . The salaries of the seven people in thousands of dollars are $25,10,19,57,53,55$, and 63 , so that the population means we want to estimate is $\mu=36.5$. If the first three of these salaries are those of bank trainees and the other four are salaries of officers in the bank, find $n_{1}$ and $n_{2}$ if the allocation is
-proportional.
