Which the sampling method reflects the following:
the person most knowledgable on subject of the study selects elements of the population that he or she feela are most representative of the population:
a. judgment sampling
b. stratified random sampling
c. cluster sampling
d. convenience sampling

A. judgment sampling

Step-by-step explanation: Judgement sampling also known as judgemental sampling is a non probability sampling technique that gives the researcher the opportunity to choose his or her sampling based on his or her knowledge of the study subject and the samples.

In judgemental samplings are likely to have some bias based on some important part of the population that may not have been identified and considered during the sampling process.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
