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.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
