(a)
Answer to Problem 16E
Explanation of Solution
Given:
The data set
Concept used:
The median is the middle number in a sorted ascending or descending list of numbers and more descriptive of that data set than the average.
Calculation:
The first quartile denoted by
Order the data and the median of the lower half.
The difference of the greatest value and the least value of the data set is different
Since the range of data set is
The other
The difference of
(b)

Calculation:
The first quartile denoted by
Order the data and the median of the lower half.
The difference of the greatest value and the least value of the data set is different
Since the range of data set is
The other
The difference of
The length of the box is longer between
So,the data is more spread out.
