Answer:
The answer is (d)= Selecting a simple random sample from each of a given number of strata formed from the elements in the population.
Stratified random sampling is a sampling method where the population has a number of distinct categories. The population can be organized into separate strata and each stratum is then sampled as an independent sub-population out of which individual elements can be randomly selected. In this case, each unit in a stratum, that is, each element in a group has the chance of being selected into the sample and there is adequate representation of minority sub-groups. With Stratified sampling, the best result occurs when elements within strata are internally homogeneous.

Step-by-step explanation:
Given that;
n=6 , m=2 , z1 is the average of the elements of x , and z2 is the average of the first three elements of x minus the average of fourth through sixth elements of x
So, Let d=n∧28, d′=n∧22.
We have nd=10, nd′=20n
so
n=10d=20d′nwhenced=2d′.
On the other hand, d is a divisor of 28, and above shows d′ is, too. As it is also a divisor of 22, the only possibilities are d′=1, d′=2, corresponding to d=2, d=4.
However, if d=2, n=20, and 20∧28=4, not 2. So the only solution is d=4, and n=40.
