Consider the demonstration problem 6.3 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?

The importance of stating the null and alternative hypotheses before conducting the test.

The importance of a type one error (p) in conducting the test

The relationship between the p value and our decision to accept or reject the null hypothesis

Respond to the following in a minimum of 175 words:

An important part of using statistics is being able to explain your results to decision makers. Imagine that you have conducted a two-sample test and determined that the difference was not statistically significant.   While one mean was 4.3 and the other was 3.9, the p level for the t test was p=.07. Your management team says, “Well, the difference may not be statistically significant, but the difference is there! Discuss how you would respond and how you would explain the purpose of the t test and significance in this case.
