Chapter 11.2, Problem 15HP

To determine

To find: The distribution for symmetric distribution and not symmetric distribution.

Answer to Problem 15HP

The distribution for symmetric distribution and not symmetric distribution is discussed.

Explanation of Solution

The example of a symmetric distribution is the restaurant.

The required diagram is shown in the below figure:

  

Figure 1

From the above graph, it is concluded that the number of customers in the restaurant for other time is same (say 9 AM to 3 PM). Only there is one peak which is at lunch time usually 12 noon.

The example of a skewed distribution is the score of students.

The required diagram is shown in the below figure:

  

Figure 2

From the above graph, it is concluded that the score of students. When the difficulty level of exam is high, then most of the students score lower marks. Only few students which are intelligent got higher marks.

Thus, the distribution for symmetric distribution and not symmetric distribution is discussed.
