The mean of a population is 50 and the median is 40. which histogram is most likely for samples from this population?

Since the mean is greater than the median, I'd expect the distribution curve to be skewed in the positive direction. In other words, there a few large outliers but fewer small outliers. It would be helpful if the answer choices were provided though.

Since no diagram is given, I'm guessing that it shows two concentric circles. The inner circle represents the pool while the annular space between the two circles represent the gravel path. So, in this problem, we have to determine the area of the annular space. We can determine this by subtracting the area of the smaller circle to the bigger circle. Knowing that the area of a circle is πr²,

Big circle = π(250/2)² = 49,087.4 ft²
Small circle = π(200/2)² = 31,415.93 ft²
Annular space = 49,087.4 ft² - 31,415.93 ft²
Annular space = 17,671.47 ft²

Therefore, the area covered by the gravel path is 17,671.47 ft².
