Question
Which is the median of the data?

Answer options with 5 options
A.
115 feet

D.
122 feet

B.
118 feet

E.
124 feet

C.
120 feet

Answer 1

B. 118 feet

To find the median of the data, we first need to arrange the heights in ascending order:
10, 10, 10, 10, 11, 11, 11, 11, 11, 11, 11, 11, 12, 12, 12, 12, 13, 13, 14, 14

There are 20 data points, so the median will be the average of the 10th and 11th values in the ordered list:
(11 + 11) / 2 = 11

So, the median height of the trees is 118 feet.
