The correct answer is B. Stratified sampling is used since the field is divided into subplots and a random sample is taken from each subplot.
Explanation:
Sampling refers to the process followed by researchers to select a group of individuals from a larger group; considering in most studies it is not possible to analyze all the population. In the case of stratified sampling, this involves dividing the general population into smaller groups, which are known as strata; after this, the researcher selects a specific number of individuals from each strata. This method guarantees the sample is selected randomly, and therefore the study is not biased. Stratified sampling was the method used in the example described because, in this, the general population (46-acre field) was divided into subplots that represent the strata. Also, after this, the researcher selected one random sample.
Answer:
<u>The equal monthly payment during 48 hours for buying a car is US$ 187.82</u>
Step-by-step explanation:
Loan from the bank to buy a car = US$ 9.015.20
Period of time to pay back the loan = 48 months
Form of payment = Equal monthly payments
Monthly payment = Loan from the bank / Period of time
Monthly payment = 9,015.20 / 48
<u>Monthly payment = US$ 187.82 (rounding to the nearest cent)</u>
<u>Each equal monthly payment during 48 months is US$ 187.82</u>
