To find the first and third quartiles of the dataset represented in the box plot, we can look at the boundaries of the two sections of the box plot.
The first quartile is represented by the lower boundary of the second section of the box plot, which is at 3.
The third quartile is represented by the upper boundary of the second section of the box plot, which is at 7.5.
Therefore, the first quartile is 3 and the third quartile is 7.5.

Use the image to answer the question.
An illustration shows a number line ranging from 0 to 12 in one unit increments. Each number is labeled and represented with a tick mark. A box plot is placed above the number line. The box is divided into two sections.
The first section of the box plot extends from 1.5 to 3. The second section of the box plot extends from 3 to 7.5. A line starts at the left side of the first section of the box plot and extends from 1.5 to 0, where it ends with a short vertical line. Another line starts at the right side of the second section of the box plot and extends from 7.5 to 12, where it ends with a short vertical line.

My apologies for the mistake. To find the first and third quartiles in a box plot, we need to look at the boundaries of the two sections of the box plot.
In this case, the first quartile is located at the lower boundary of the first section of the box plot, which is at 1.5.
The third quartile is located at the upper boundary of the second section of the box plot, which is at 7.5.
Therefore, the first quartile is 1.5 and the third quartile is 7.5.
In this case, the first quartile is located at the lower boundary of the first section of the box plot, which is at 1.5.
The third quartile is located at the upper boundary of the second section of the box plot, which is at 7.5.
Therefore, the first quartile is 1.5 and the third quartile is 7.5.
Enter the values to complete the box plot of dataset 23, 24, 25, 26, 27, 28.(2 points)
To find the values needed to complete the box plot of the dataset {23, 24, 25, 26, 27, 28}, we first need to find the first quartile (Q1) and the third quartile (Q3) of the dataset.
Step 1: Order the dataset in ascending order:
23, 24, 25, 26, 27, 28
Step 2: Find the median, which is the middle value of the dataset:
Since the dataset has an even number of values, the median is the average of the two middle values: (25 + 26) / 2 = 25.5
Step 3: Find Q1 and Q3:
For Q1, we look at the values below the median:
Q1 = (23 + 24) / 2 = 23.5
For Q3, we look at the values above the median:
Q3 = (27 + 28) / 2 = 27.5
Now, we have the values to complete the box plot:
Lower whisker: 23
Q1: 23.5
Median: 25.5
Q3: 27.5
Upper whisker: 28
So, the completed box plot for the dataset {23, 24, 25, 26, 27, 28} would have the following values:
Lower whisker: 23
Q1: 23.5
Median: 25.5
Q3: 27.5
Upper whisker: 28
Step 1: Order the dataset in ascending order:
23, 24, 25, 26, 27, 28
Step 2: Find the median, which is the middle value of the dataset:
Since the dataset has an even number of values, the median is the average of the two middle values: (25 + 26) / 2 = 25.5
Step 3: Find Q1 and Q3:
For Q1, we look at the values below the median:
Q1 = (23 + 24) / 2 = 23.5
For Q3, we look at the values above the median:
Q3 = (27 + 28) / 2 = 27.5
Now, we have the values to complete the box plot:
Lower whisker: 23
Q1: 23.5
Median: 25.5
Q3: 27.5
Upper whisker: 28
So, the completed box plot for the dataset {23, 24, 25, 26, 27, 28} would have the following values:
Lower whisker: 23
Q1: 23.5
Median: 25.5
Q3: 27.5
Upper whisker: 28
23.5 and 27.5 are incorrect
I apologize for the error. Let's recalculate the first and third quartiles for the dataset {23, 24, 25, 26, 27, 28}.
Step 1: Order the dataset in ascending order:
23, 24, 25, 26, 27, 28

Q1 = (23 + 24) / 2 = 23.5
For Q3, we look at the values above the median:
Q3 = (27 + 28) / 2 = 27.5
Therefore, the first quartile (Q1) is 24 and the third quartile (Q3) is 27.
Step 1: Order the dataset in ascending order:
23, 24, 25, 26, 27, 28
Step 2: Find the median, which is the middle value of the dataset:
