(a)
To Describe:The data in histogram.
(a)

Answer to Problem 11PPS
Most of the countries whose medal count winners for the summer Olympics re in the range of
The number of countries who won more than hundred medals is greater than number of countries who won less than hundred medals in summer Olympics.
There are total of
Explanation of Solution
Given: The histogram given below shows the total number of medals won by the top ranking country per year for the summer Olympics from
From the histogram, it is concluded that
Most of the countries whose medal count winners for the summer Olympics re in the range of
The number of countries who won more than hundred medals is greater than number of countries who won less than hundred medals in summer Olympics.
There are total of
(b)
To Describe: How the histogram was constructed incorrectly.
(b)

Answer to Problem 11PPS
The interval size of the horizontal axis i.e. the number of medals in the data is not uniform
Explanation of Solution
Given:The histogram given below shows the total number of medals won by the top ranking country per year for the summer Olympics from
The interval size of the horizontal axis i.e. the number of medals in the data is not uniform.
(c)
To Describe: How would you change the histogram so that it is no longer constructed incorrectly?
(c)

Answer to Problem 11PPS
By rearranging the data if number of medals in the uniform interval data sets.
Explanation of Solution
Given:The histogram given below shows the total number of medals won by the top ranking country per year for the summer Olympics from
When the interval size of the horizontal axis is uniform, the histogram is constructed correctly.
So
By rearranging the data if number of medals in the uniform interval data sets the histogram will no longer incorrect.
