An illustration shows two sets of number lines with dot plots. They are titled teachers and students showing number of siblings in each respectively. The first number line is for teachers with arrows on both the ends. It ranges from 0 to 10 in increments of 1. It shows 3 closed circles over the 0 marking, 3 closed circles over the 1 marking, 4 closed circles over the 2 marking, 3 closed circles over the 3 marking, 2 closed circles over the 4 marking, 3 closed circles over the 5 marking, 1 closed circle over the 6 marking and 1 closed circle over the 9 marking. The second number line is for teachers with arrows on both the ends. It ranges from 0 to 10 in increments of 1. It shows 1 closed circle over the 0 marking, 2 closed circles over the 1 marking, 4 closed circles over the 2 marking, 5 closed circles over the 3 marking, 4 closed circles over the 4 marking, 1 closed circle over the 5 marking, 2 closed circles over the 6 marking and 1 closed circle over the 7 marking.

The true statement is: "The median number of siblings for students is higher than the median number of siblings for teachers."

Reason: Teachers' median = average of the 10th and 11th values = (2 + 3)/2 = 2.5. Students' median = 3 (both 10th and 11th values are 3). So 3 > 2.5.
