Explanation of Solution
Given:
Figure is:
Calculation:
Consider, the numbers are 2800, 3000, 3200, 3400, 3800.
The figure could be constructed as:
b.
To explain: The reason of sample range of above constructed not being equal to the actual distribution.
b.
![Check Mark](/static/check-mark.png)
Explanation of Solution
The range of both the distributions is not equal because the provided data plot has the range of 500 samples while the actual one has the sample range for the all the sample of 500 size.
