Answer:
"B. about half the days in march had average temperatures either below 60 or above 73 degrees"
Explanation:
To answer this question, note that a box plot is usually divided into quartiles, each representing approximately 25% each.
In the box plot above,
*about 25% (Q1) represents days with temperature of 60° and below. This is about ¼ of the days in March.
*About 25% (Q2) represents days with temperature between 61° and 68°. That's about ¼ of the days in March
*About 25% (Q3) represents days with temperature between 70° and 73°. That's about ¼ of the days in March
*About 25% (Q4) represents days with temperature between 74° and 82°. That's about ¼ of the days in March
*Coldest day in March has a temperature of 54°
*Hottest day in March is 82°
From the options given, the only statement that is true is "B. about half the days in march had average temperatures either below 60 or above 73 degrees"
¼ of the Days in March has temperatures below 60° (Q1), while ¼ of the days in March has temperatures above 73° (Q4). Therefore, ¼+¼ = ½ of the days in March having average temperatures either below 60 or above 73 degrees.
