The Paralyzed Veterans of America is a philanthropic organization that relies on contributions. They send free mailing labels and greeting cards to potential donors on their list and ask for a voluntary contribution. To test a new campaign, they recently sent letters to a random sample of 100,000 potential donors and received 4781 donations. (a) Give a 95% confidence interval for the true proportion of those from their entire mailing list who may donate. (b) A staff member thinks that the true rate is 4.5%. Given the confidence interval you found, do you find that rate plausible? (a) What is the 95% confidence interval? The 95% confidence interval is from % to %. (Round to two decimal places as needed.) (b) Given the confidence interval you found, is the proposed true rate, 4.5%, plausible? The proposed true rate \boxed{} plausible because the confidence interval \boxed{} 4.5%

8. A certain rigid body rotates about a fixed origin. Relative to that origin, a point A at $\vec{r}_A = a\hat{z}$ has instantaneous velocity $\vec{v}_A = 2v_0\hat{x} - v_0\hat{y}$. At the same instant, point B at $\vec{r}_B = a\hat{x}$ has instantaneous velocity $\vec{v}_B = v_0\hat{y} - 2v_0\hat{z}$. (a) What is the spin $\vec{\omega}$ at that moment? (b) What is the velocity of point C at location $\vec{r}_C = a\hat{x} + a\hat{z}$?
