Answer 1

20

Explanation:

Answer 2

Range = 20

Explanation:

First we have to define range.

The range gives us the spread of data. It can also be called the area of variation.

The range is calculated by subtracting lowest value of data from highest value of data.

The formula for range is:

Range = Highest Value - Lowest Value

In the given data,

Lowest value = 22

Highest value = 42

So,

Range = 42 - 22

= 20

Hence, the range of given data is 20 ..
