Hello! I need accounting homework (4 sections) done , and a statistics project due today! Please message me if you are able.
Thank you,
Kelly
Will pay $200 for both assignments
50 for statistics // 150 for accounting
Data Project
Statistics – Spring 2013 Professor K. Hawryluk
Due date: April 22, at the beginning of class. There will be 5 points deducted for every day late and the latest that the project will be accepted is the beginning of the final exam on May 1
It is expected that you will present a ‘professional’ looking document for this project. Be sure to answer all questions with simple declarative sentences. Present 2 copies of this project with one staple in the top left corner of each copy. At the top of the first page place you name, and the Course Name. (No Binders). neatness counts! English counts! Read these directions carefully because adhering to them counts too!
You may get assistance on this project from any source, but the final presentation must be your own work. This presentation is assumed to be directed to a reader who has some knowledge of statistics. It is not necessary to show steps in calculator solutions but it is necessary to present formulas and identify variables.
Reproduce all questions as presented. Completely solve the problem, show all formulas used and discuss why they were chosen for the particular problem. If conditions must be met state them and show how they are met. Also show the results of a calculator approach to solving the problem if appropriate. Discuss the P-value method as well as the traditional method where appropriate and present a simple graph to illustrate your discussion. Be sure to answer the question(s) asked (a number is not an answer) in sentence form.

· In clinical trials of Nasonex, 3274 adult and adolescent allergy patients (12 years and older) were randomly divided into two groups. The patients in Group 1 (experimental group) received 200 meg of Nasonex, while the patients in Group 2 (control group) received a placebo. Of the 2103 patients in the experimental group, 547 reported headaches as a side effect. Of the 1671 patients in the control group, 368 reported headaches as a side effect. Is there significant evidence to support the claim that the proportion of Nasonex users that experienced headaches as a side effect is greater than the proportion in the control group at the α = 0.05 level of significance?
· Concrete Strength: An engineer wanted to know whether the strength of two different concrete mixtures differed significantly. He randomly selected 9 cylinders , measuring 6 inches in diameter and 12 inches in height, into which mixture 67-0-301 was poured. After 28 days , he measured the strength, (in pounds per square inch) of the cylinder. He also selected 10 cylinders of mixture 67-0-400 and performed the same test. The results are as follows:
67-0-301 mixture: 3960, 4090, 3100, 3830, 3200, 3780, 4081, 4040, 2940.
67-0-400 mixture: 4070, 4890, 5020, 4330, 4640, 5220, 4190, 3730, 4120, 4620.
Plots indicate that the data are approximately normal and boxplots indicate that there are no outliers.
a) Test the claim that mixture 67-0-400 is stronger than mixture 67-0-301 at the 0.05 level of significance.
b) Construct a 90% confidence interval about μ400 – μ301 and interpret the results.
