Final answer:
The value of the most common sample mean cannot be determined without sample data.
Step-by-step explanation:
The value of the most common sample mean can be calculated using the formula for the mean (also known as the average).
To calculate the mean, you add up all the values in the sample and then divide it by the number of values in the sample. In this case, since the question does not provide any sample data, it is not possible to determine the value of the most common sample mean.
Therefore, none of the given options (A. 54, B. 60, C. 8, D. 36) can be considered as the correct answer.
