Independent (unpaired) t-test
Explanation:
In research methods, the term "independent (unpaired) t-test" is described as a process that is being used by the researcher or the investigator when two different sets of identically distributed and independent samples are being obtained and henceforth "one from each of the two" different populations are being compared or analyzed. Therefore, according to the given scenario, the researcher or the investigator discovers two different "independent samples" and utilizes the "unpaired type of the t-test".
In the question above, the most appropriate analysis would be independent (unpaired) t-test.
