The members of a population have been numbered 1–1000. A sample of size 50 is to be taken from the​ population, using stratified random sampling with the proportional allocation. The strata are of sizes 100​, 400​, 200​, and 300​, where stratum​ #1 consists of the members of the population numbered 1–100​, stratum​ #2 consists of the members  of the population numbered 101–500​,and so forth. Determine the sample sizes that will be taken from the strata.
