Explain the normal distribution and how useful it is in statistics?
See Attachment for below problem and Respond in a minimum of 150 words:
Consider the demonstration problem 6.3 (attached) which uses a normal distribution to determine the probability associated with generating between 3.6 and 5 pounds of waste per year.
Discuss any one of the following concepts associated with this problem.
- What are the “clues” that the problem can be solved with the use of the normal distribution?
- What is the relationship between the x value (e.g 3.6) and the z score?
- How is the probability of the event (3.6 to 5 pounds of waste) related to a specific area under the curve?
- How do we determine the area between 2 z values?
