Question
Chapter 5, Problem 16E
a)
To determine
To compare the distributions of prices over the three years.
a)
Expert Solution
Explanation of Solution
Given:
The shape of the distributions of 2002 and 2004 is roughly symmetric. The shape of the distribution of 2003 is right skewed. Also, there are outliers in the bottom of the year 2002 and the single outlier in the top of the year 2004.
b)
To determine
To the year which have least stable prices.
b)
Expert Solution
Answer to Problem 16E
The least stable prices appear in 2004.
Explanation of Solution
Given:
The higher the variability leads to least stable prices. Therefore, the spread of the 2004 seen higher as compare to other years. Hence, least stable prices appear in 2004.
