Final answer:
The mean height being lower than the median height suggests that there are a few short girls in the group.
Step-by-step explanation:
The given information about the mean and median heights of a group of girls can provide some insight into whether there are a few short or tall girls in the group.
If the mean height is lower than the median height, it suggests that there are a few shorter girls in the group. In this case, since the mean height is 5 ft 1 in and the median height is 5 ft 4 in, the mean is lower than the median, indicating that there are a few short girls in the group.
Therefore, the answer to the question is: a) Few short girls.
