Solution
Let's analyzeLet's the analyze box the-and-whisker box plots-and for City-wh A andisk City Ber to plots answer the questions to answer the:
- ** questionsQuestion (a)::
Which city### ( hada more noon temperatures) above Which city77°F had?**
- more ** noon temperaturesObservation** above: City A's third quart77ile°F (? upper- part ** ofCity A** the box:) The is box above plot for77°F, indicating more City data A points above extends 77 above°F than City77 B,°F (part whose of the third quartile third and quart theile is below this whisk mark. er ).
- -Answer: ** CityCity B A had** more: noon temperatures above 77°F.
- Question The ( upperb quart):ile Which for City B city does not had the reach highest noon temperature ? 77°F , - so fewer ** pointsObservation**: are The highest data point above (77°Fthe maximum compared) for to City A City is around 95 A. °F-, whereas ** forAnswer City** B it: is around ** 90°F.

###Question (c (): Which city hadb) a Which city larger had median noon temperature the?
- highest ** noonObservation temperature**? : The- median ** line forCity City B A appears** to be: around The75°F maximum, value while (end City A of's median is approximately the 80 whisk°F. er ) - Answer: is City around A had90 a larger°F median. noon- temperature **.
- QuestionCity (d B): Which city: had The noon maximum temperatures value with ( aend larger inter ofquart theile range whisk (IerQR)?)** is - around ** Observation**:95 The°F IQR. is- the length of ** the boxAnswer (difference: ** between the thirdCity and B first quart had theiles highest noon temperature). City.
A's IQR is wider than that of City B.
- Answer: City A had a larger IQR.
Would you like further clarification on any of these answers? Here are five questions to deepen your understanding:
- What is the significance of the median in a box-and-whisker plot?
- How is the interquartile range (IQR) calculated?
- Why is it useful to analyze quartiles in data?
- What can outliers### in a (c box)-and Which-wh city had a larger median noon temperature? -isk City A: The median (middle line of the boxer) is around 75°F.
- City B: The median plot is around 70°F.
- Answer: indicate City A had a larger median noon temperature.

Here are 5 related questions that expand on this topic:
- How do you calculate the median from a box-and-whisker plot?
- What does the IQR tell you about data spread, and why is it useful?
- How can outliers be identified using a box-and-whisker plot?
- What information do the whiskers in a box plot represent?
- How do box-and-whisker plots differ from other visual data representations like histograms?
Tip: Always check the whisker lengths and outlier points in a box-and-whisker plot to better understand the distribution of the data.
