Answer 2

Answer:

Range = 20

Median = 15

Step-by-step explanation:

Range = 32 - 12 = 20

In order to find the median of the given data let us arrange them in ascending order.

12, 13, 13, 15, 16, 19, 32

Here, number of observations n = 7

$median = \bigg(\frac{n + 1}{2}\bigg) ^{th} term\\ = \bigg(\frac{7 + 1}{2}\bigg) ^{th} term \\ = \bigg(\frac{8}{2}\bigg) ^{th} term \\ = 4th \: term \\median = 15$
