Which sample size of a population of 200 is most likely to give a reliable conclusion?
10
30
50
80

80

Step-by-step explanation:

The sample size is very important if we want to conduct a research of any interest. The larger the sample size it will make research results more accurate and reliable to the researcher.

Also to detect a statistical difference with a certain strategy require a larger sample size.

From the given options 80 is the maximum value , so it must be representing the largest sample size .

Therefore, the sample size of a population of 200 is most likely to give a reliable conclusion is 80.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
