I need a person who know University Level BUSINESS STATS

I have 15 - 20 Business Stats Questions in a online website. I want someone to do all those correctly. So please understand this project description very carefully. This questions can be done if you are fluent in understanding English since questions trying to trick you. If you get at least 1 character wrong then the entire question will be wrong. Use a pencil and paper always before applying the final answer for the website. This is how I am gonna pay. I will only give 1 attempt and if you fail to score more than 90% then you get $10 thats it. But If you score more than 90% you get $50. This is a job for a Business Stats Master.
