(a)
Answer to Problem 2CYU
More than 50%
Explanation of Solution
Given information:
The number of calories burned for 15 minutes of exercise for various activities is shown.
Calculation:
The given box and whisker plot shows number of calories burnt for 15 minutes of exercise. It is required to know that what percent of the activities burn fewer than 98 calories.
Locate 98 in the number scale of the given box and whisker plot. Note that box and whisker plot separates the data into four excluding outlier. The distance between minimum and lower quartile comprise 25%, lower quartile to median comprises 25%, median to upper quartile comprises 25%and and upper quartile to maximum comprises 25%. Thus, more than 50% of activities burn fewer than 98 calories.
Therefore, the answer is: more than 50%.
(b)
To find; the length of the box tell about the data.
(b)
Answer to Problem 2CYU
More than 50%
Explanation of Solution
Calculation:
The given box and whisker plot shows number of calories burnt for 15 minutes of exercise. It is required to know what percent of the activities burn fewer than 98 calories.
Locate 98 in the number scale of the given box and whisker plot. Note that box and whisker plot separates the data into four parts excluding outlier. The distance between minimum and lower quartile comprise 25%, lower quartile to median comprises 25%, median to upper quartile comprises 25%and upper quartile to maximum comprises 25%.
