Assignment 6 Julian Jordan STAT 4210 b. Hypotheses: i. H 0: Becoming an organ donor and the default choice offered to the participants are independent of each other. ii. H A: Becoming an organ donor and the default choice offered to the participants are associated. c. Test Statistic: 24.284 d. P-Value: 0.0001 e. Conclusion: If becoming an organ donor and the default choice offered to the participants are independent of each other, then a test statistic of 24.284 or higher would only occur about 0.0001 % of the time. With a p-value of approximately 0, we have sufficient evidence to reject the null hypothesis, and conclude that there is an association between becoming an organ donor and the default choice offered to the participant.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
