Question

A dataset contains 10 observations such that the maximum and the minimum values are 30 and 17 respectively. Which among the following can be the mean of the dataset?

• A. 15
• B. 17
• C. 25
• D. 33

Answer 1

The correct option is C 25

The arithmetic mean always lies between the lowest and highest observations of the data.

This implies that the mean of the given dataset lies between 17 and 30. From the given options, only 25 lies in between 17 and 30.

Thus, 25 is the required mean.
