Question
Researchers are working with a cohort of 1,313 people. They waited couple years to see which ones would expose themselves to some possibly harmful thing and 851 of them did. The other 462 did not have (report) the exposure. Then they waited a few more years and observed which people got the disease and which did not. The following table summarizes the results.
No disease Got disease Total
Not exposed 308 154 462
Exposed 142 709 851
Total 450 863 1313
a. Compute the odds ratio for getting the disease. Interpret this odds ratio in words to answer the question ‘Whether a certain disease is associated with a certain exposure?’
b. Calculate the Relative Risk. Interpret this result.

WHAT OUR STUDENTS SAY
I was really very poor at drawing phase diagrams in my material science course. In fact that was the first time I looked for help from HwA. The result was fantastic. The material science experts knew what to deliver just after receiving the request and I didn’t have to worry since then.

Great assistance!!! Thank you guys for all your support. I love the way you dealt with my every instruction and I’m very much satisfied with the work. As I had difficulties managing time for studies and job, you really saved both.
Brendon Student
My professor gave an assignment where I had to make a marketing plan for a daily use product in the markets of Hastings, New Zealand. I was unsure whether anyone in the internet will be able to guide me with such accurate details. However, to my surprise I found out that HwA not only have separate Kiwi assignment helpers but there are marketing assignment experts also. I definitely got good grades and I am very happy with my results.
Timothy Young Student
I was looking for help writing my case study on Stock Valuation. The case study needed specific stock valuation analysis work and I needed someone with good hold on the subject to write the case study analysis. At HwA I was paired with a finance assignment expert who had extensive industry experience. The quality of the assignment was absolutely brilliant and helped me score an A.
Tim Branagh Student
First impression leaves a very deep mark in somebody’s mind and my research proposal, written by one of the experts of HwA was the first impression which impressed my dissertation advisor in my college of Hamilton. After the research proposal I took further help in the actual research paper and got excellent grades.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
