We will answer any question specifically for you for only
Step 1: Problem Definition
What problem have you been asked to address? This is not a statistics question, therefore the answer is not about performing a certain calculation.
What is the objective or outcome this work should produce? Again, this is not a statistics question, and will not be answered with a statistical approach. (Refer to the answer to question 1 and 2 when writing your thesis statement.)
What statistical approach will you use to address this problem? AND Why does this approach provide you insight into addressing the problem? What does it let you know about the problem that can inform a decision?
To whom you have been asked to address this memorandum?
What is each of the addressees is likely to need from reading the memorandum? (This is a critical thinking exercise, ask yourself what the addressees' responsibilities are and use that to think about what they need to know from you. If you are not familiar with these corporate roles lookup explanations of each. There are links to an explanation for each in the problem description below. )

For the deliverable for this assignment, submit one document: the memorandum elements at the beginning, followed on a separate page, by an appendix with the problem definition questions.
In this section, you will find a description of the problem, requested recommendation and audience for the final memorandum for this assignment.
You are a line manager in Superior Car Part’s Ellisville manufacturing facility. The company produces automotive parts, and you have responsibility for the line producing steel shafts for the gearbox manufactured in the Ellisville Plant. The acceptable dimension of the shaft is 2.5±0.05 inches in diameter with the most desirable product having a diameter of exactly 2.5 inches. The current equipment is approaching the end of its useful life and needs to be replaced. Two vendors are trying to sell your company, Superior Car Parts Incorporated, their machines for the shaft-machining task. You have been asked to assess the machines from each vendor, and to make a recommendation for a machine vendor supported by a justification for your decision.
You asked both vendors to supply data on the machining accuracy of their machines for the given task. Both vendors machined 100 shafts, collected data, plotted histograms, fitted the histograms with normal distributions and supplied you with their findings.
Let X= diameter in inches of the gearbox shaft
Abano Machines Inc.: X has a normal distribution with a mean of 2.49 and a standard deviation of 0.030
Li Equipment Corp.: X has a normal distribution with a mean of 2.53 and a standard deviation of 0.015
Audience: You are creating this document for the company’s Chief Operating Officer (Links to an external site.), Lena George, and copying the Chief Financial Officer, (Links to an external site.) Amita Kohli. Documents involved in major financial decisions like this may also be distributed by the addressees to other executives and the corporate board members.
