Question

Sadie has worked at a cell phone store for nine months. Her sales are denoted by the set {5, 7, 8, 21, 15, 18, 5, 13, 14}. Which 5-number summary represents the data set? (2 points)

Answer 1

Here we go:

Minimum: 5

Maximum: 21

Median: 13

Quartile 1: 6

Quartile 3: 16½

I had to take a very long look at it, and I cannot believe how stupid I was.

Anyway, I am joyous to assist you anytime.

Answer 2

Answer:

Min.         1st Qu.        Median         Mean             3rd Qu.          Max.  

5.00        7.00            13.00             11.78              15.00             21.00

Step-by-step explanation:

The five things that include in five-number summary are:

1. Minimum Value

2. First Quartile (Q₁)

3. Median

4. Third Quartile (Q₃)

5. Maximum Value

So,  

1. Minimum Value is the lowest value of the data. And it is the first value after arranging the data in ascending order.

Minimum Value = 5  

2. If the data is arranged in ascending order than First Quartile is the central value of the Minimum value and Median of data.

First Quartile = Q₁ = 7  

3. The middle value of the data after arranging the data in descending or ascending order is called the median.  

Median = 13

4.  Third Quartile: If the data is arranged in ascending order than it is the central value of the Median and Maximum Value of data.

Third Quartile = Q₃ = 15

5. Maximum Value can be found by arranging the data in ascending order, the last value we will get is the maximum value..

Maximum Value = 21.
