4. Generalize the Bayesian analysis of medical screening given in class. Let a rare disease D occur with probability P(D) with δ small. The test for this disease is accurate such that the probability of a correct result is 1-e, with e small. Derive formulas for the probabilities of a true positive P(D|+) and a false positive, P(D|+). For this screening to be useful at a given δ, what is required of ε ?

4. Generalize the Bayesian analysis of medical screening given in class. Let a rare disease D occur with probability P(D) = δ, with δ small. The test for this disease is accurate such that the probability of a correct result is 1-e, with e small. Derive formulas for the probabilities of a true positive P(D|+) and a false positive, P(D'l+). For this screening to be useful at a given δ, what is required of e ?

2. A device consists of two redundant subunits; only one needs to be working for the device to function. The first subunit has two parts Wi and W2, and the second has two parts W3 and W4. In each subunit, both parts must function for the subunit to work. The four parts are independent identical and equally reliable, with probability p- 0.9 of functioning. (a) What...

Please With recognizable hand writing. Thank you.
Question 2. (40 Points) Consider a BPSK modulation with 2 signals: 2 where ??(t) and ?1 (t) for t E 10, T,l form a set of orthonormal basis functions. Signals so(t) and si(t) are equiprobable. We suppose that the transmission channel introduces an additive white Gaussian noise n(t). Thus, the received signal is given by r(t) s(t)+n(t), where the additive white Gaussian noise has power spectral density No/2. toT Y-X+N rit) a(t)+n(t) Figure...

Awarding road contracts. A state Department of Transportation (DOT) recently claimed that each of five bidders received equal consideration in the awarding of two road construction contracts and that, in fact, the two contract recipients were randomly selected from among the five bidders. Three of the bidders were large construction conglomerates and two were small specialty contractors, Suppose that both contracts were awarded to large construction conglomerates. a. b. What is the...

not add up to 1.0 and that is fine.
Problem #1 (8 points) Suppose you have gone bowling with an excellent player who bowls a strike (ie when they hit all of the pins) 73% of the time. By the fourth frame, this person realizes that they can clincha first place in a local tournament by bowling 3 consecutive strikes. What is the likelihood of this happening! Problem #2:...
