Question No 1

The range of rainfall for the highland storms is 44 mm

Question No 2

The range of rainfall for the lowland storms is 30 mm

Step-by-step explanation:

Question 1

What is the range of rainfall for the highland storms?

2 46 8 10 12 14 16 18 20 22 24 26 28 30 32

First we arrange data in ascending order.

2 8 10 12 14 16 18 20 22 24 26 28 30 32 46

Now we have to find range. The formula used is:

In the given data set:

Maximum Value = 46

Minimum Value = 2

Finding range by putting values in the formula:

So, the range of rainfall for the highland storms is 44 mm

Question 2

What is the range of rainfall for the lowland storms?

2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

First we arrange data in ascending order.

The data is already arranged in ascending order

Now we have to find range. The formula used is:

In the given data set:

Maximum Value = 32

Minimum Value = 2

Finding range by putting values in the formula:

So, the range of rainfall for the lowland storms is 30 mm
