Answer 1

Given the data set:

`23,17,14,21,23,18,29,20,13`

a. 1. You need to order it from least to greatest:

`13,14,17,18,20,21,23,23,29`

2. You can identify the Range. Therefore, the minimum point of the whisker must be on:

`13`

And the maximum point on the whisker must be on:

`29`

3. Determine the Median of the whole data set (the middle value in the data set). Since there 9 values in the set, you can determine that:

`Median=20`

4. Find the Median of the bottom half part of the data:

`Median_(bottom)=17`

5. And the Median of the top half is:

`Median_(top)=23`

Knowing all that data, you can create the Box Plot:

b. By definition, the first quartile divides 25% of the data. Therefore, you can determine that the percentage of the data that is above the first quartile is:

`75\text{\%}`

c. By definition, the second quartile divides 50% of the data. Therefore, the percentage of the data that is below it is:

`50\text{ \%}`

Hence, the answers are:

a.

b.

`75\text{\%}`

c.

`50\text{\%}`
