(d) The median height of the boys.​

Answer 1

(1.) height of the tallest boy is → 154 cm

(2.) The hieght of the shortest boy→ 128cm

(3.) Range→ highest value-lowest value

Answer 2

Answer:

(a) The height of the tallest boy is 154.

(b) The height of the shortest boy is 128.

(c) The range of the given data is 26.

(d) The median height of the boys is 142.5

Step by step explanation:

How to find range if data?

Highest value - lowest value

=154 - 128

=26

How to find median of the data?

First step: To arrange the numbers in ascending order.

128,129,136,138,140,142,142,143,144,144,146,146,152, 154

Second step: Find the middle number.

142 and 143.

Here,there are two numbers middle.

So, 142+143/2

285/2

142.5

Hope this helps you ✌️........
