Accepted Solution

A:

The cases where by the mean is greater than the median is shown common for the distribution that is skewed to the right (that is, bunched up toward the left and with a tail stretching toward the right ). The example that characterizes the above property is [a], this is because we have been given a set of triplets whose age is lower than that of their brother. This implies than there are high chances that the mean will be above the median
