The number of hours Darla baby-sat her sister each week for the last 12 weeks is shown below.
12, 17, 14, 18, 20, 16, 10, 13, 21, 9, 10, 22
Which box-and-whisker plot accurately represents the given data?
I need help please
Hi again, @Happyperson85, since we can't see the box-and-whisker plots we can't really help you. But, if you need help THAT bad, you can call your teacher and ask her/him for help. When I do that, my teacher always helps me find the correct answer. ._.
Any answers yet? no. ok.
The answer is the one with no red lines outside the box aka the first dot starts on 9, middle dot on 15, and last dot on 22 (Between 21 and 23).
I don't see in box and whisker plots.
So what is the answer?
idk what is the answer
@fat why would the middle dot be on 15 if theres no 15 in the data?
To create a box-and-whisker plot for the given data, you need to follow these steps:
1. Organize the data in ascending order:
9, 10, 10, 12, 13, 14, 16, 17, 18, 20, 21, 22
2. Find the minimum value (the lowest data point):
The minimum value is 9.
3. Find the first quartile (Q1):
Q1 is the median of the lower half of the data. In this case, the lower half is:
9, 10, 10, 12, 13, 14
The median of this set is (10 + 12)/2 = 11.
So, Q1 is 11.
4. Find the median (Q2):
The median is the middle value of the data. In this case, the data set has an even number of elements, so the median is the average of the two middle values:
14 and 16
The median is (14 + 16)/2 = 15.
So, Q2 is 15.
5. Find the third quartile (Q3):
Q3 is the median of the upper half of the data. In this case, the upper half is:
17, 18, 20, 21, 22
The median of this set is (18 + 20)/2 = 19.
So, Q3 is 19.
6. Find the maximum value (the highest data point):
The maximum value is 22.
Now that we have the quartiles and the minimum and maximum values, we can create the box-and-whisker plot.
Based on this information, the correct box-and-whisker plot should have the following details:
- The left whisker should extend to 9.
- The bottom of the box should correspond to Q1 (11).
- The median line should be at Q2 (15).
- The top of the box should correspond to Q3 (19).
- The right whisker should extend to 22.
Please note that I cannot show you the actual plot as I am a text-based AI bot. You can refer to a graphing software/tool or consult a statistics resource to find the accurate representation of the box-and-whisker plot based on the given data.
