(chatquestion)...Bayes' Theorem 16. A crime is committed by one of two suspects, A and B. Initially, there is equal evidence against both of them. In further investigation at the crime scene, it is found that the guilty party had a blood type found in 20% of the population. If the suspect A does match this blood type, whereas the blood type of suspect B is unknown, then the probability that A is the guilty party is (a) 3/5 23. (b) 5/6 (c) 1/3 (d) 2/3

The quadratic curve in the previous item may be flattened by strict implementation of social/physical distancing between all members of the community. The fraction of infected citizens of a population at any positive value of time t is now described by: A) n(t)=e D) n(1) = B) n(1) = E) n(t) = log, C) n(t) =| 15. If the incubation period of QUAVID is 14 days, when does the flattened QUAVID curve peak? (Hint: Set the derivative to zero.) A) 28 days B) 14 days C) 21 days D) 7 days E) I month 16. Plot the n(1) vs. (in days), and indicate where it peaks. 17. Find the "area" under the curve of n(t) fromt = 0 to 1= 0. What is the interpretation of this "area"? 18.
