Question

Could u plz make sure about numbers inside the graph is difficult to conduct sample surveys on sensitive issues because many people will not answer questions if the answers might embarrass them. Randomized response is an effective way to guarantee anonymity while collecting information on topics such as student cheating sexual behavior. Here is the idea. ask a sample students whether they have plagiarized term paper while in college, have each coin or heads and they have plagiarized, they are to answer "No." otherwise they private. the coin or Nst the coin toss, tut the researchers can use a proper randem sampte with are to give "Yes" as their answer. only the student knows whether the answer reflects the truth follow-up for nonresponse and other good sampl practices. Suppose in fact the is o3that a randomly chosen student has a day in which the first stage is tossing the coin and the second the truth about plagiarism. The outcome at the end of each branch is the answer given to the randomized response what is the probability of a "No" answer in the randomized response poli?

Explanation / Answer

No Box will have 0.7, since P(No box) = 1-P(Yes box) = 1-0.3 =0.7

Now the child node of No box will have 0.5*0.7 = 0.35

Child node of Yes box = P(Heads)*P(Yes box) = 0.5*0.3=0.15
