(a) The city with a larger median room temperature is city B.
(b) The city having the highest noon temperature is city B.
(c) The city having the noon temperatures with a higher interquartile range is city A.
(d) The city having more noon temperatures that 81°F is city B.
In the given question, the noon temperatures for two cities, A and B, recorded over a month are shown via the box-and-whisker plots.
We are asked to use it and answer the questions:
(a) The median of data is represented by the line in the box of the box-and-whisker plot. Thus,
The median noon temperature for city A is 73°F.
The median noon temperature for city B is 76°F.
Thus, the city with a larger median room temperature is city B.
(b) The highest temperature is seen as the end point of the whiskers. Thus,
The highest temperature for city A is 85°F.
The highest temperature for city B is 92°F.
Thus, the city having the highest noon temperature is city B.
(c) The interquartile range is the difference between the end line of the box and its start line. Thus,
The interquartile range for city A is (81 - 64)°F or 17°F.
The interquartile range for city B is (81 - 68)°F or 13°F.
Thus, the city having the noon temperatures with a higher interquartile range is city A.
(d) From the given box-and-whisker plots, we can see that after 81°F, city B has a long whisker, showing more outliers.
Thus, the city having more noon temperatures that 81°F is city B.
