12. Let 0 denote the proportion of registered voters in alarge city who are in favor of a certain proposition. Sup-pose that the value of 0 is unknown, and two statisticiansA and B assign to 0 the following different prior p.d.f'sŠA(O) and Šp(0), respectively:ŠA(O) = 20 for 0 < 0 < 1,ŠB(0) = 403 for 0 < 0 < 1.In a random sample of 1000 registered voters from the city,it is found that 710 are in favor of the proposition.a. Find the posterior distribution that each statisticianassigns to 0.b. Find the Bayes estimate for each statistician basedon the squared error loss function.c. Show that after the opinions of the 1000 registeredvoters in the random sample had been obtained, theBayes estimates for the two statisticians could notpossibly differ by more than 0.002, regardless of the number in the sample who were in favor of the prop-osition.

Suppose that Fred, a United States politician from a large western state, wants to create a new law that would require children under the age of 16 to be accompanied by an adult at all times in public places. Based on previous voting records, Fred believes that he could gain the support of 2525% of likely voters. To test his hypothesis, Fred conducts a random survey of 12001200 likely voters and asks if they would support his proposition. Let ?X denote the number of likely voters in Fred's sample that pledge their support, assuming that Fred's belief that 25%25% of likely voters would support his proposal. Which of the following statements are true about the sampling distribution of ?X? -The sampling distribution of ?X is approximately binomial with ?=1200n=1200 and ?=0.25p=0.25. -The sampling distribution of ?X is exactly normal with ?=0.5μ=0.5 and ?=0.0125σ=0.0125. -The sampling distribution of ?X is exactly binomial with ?=1200n=1200 and ?=0.25p=0.25. -The sampling…
A large shipment of computer chips comes with a guarantee that it contains no more than15% defective items. If the proportion of defective items in the shipment is greater than 15%,the shipment may be returned. You draw a random sample of 10 items. Let X be the numberof defective items in the sample. a. If in fact 15% of the items in the shipment are defective, what is P(X ≥ 2)?b. Based on the answer to part (a), if 15% of the items in the shipment are defective,would 2 defectives in a sample of size 10 be an unusually large number? c. If you found that 2 of the 10 sample items were defective, would this be convincingevidence that the shipment should be returned? Explain. d. If in fact 15% of the items in the shipment are defective, what is P(X ≥ 7)? e. Based on the answer to part (d), if 15% of the items in the shipment are defective,would 7 defectives in a sample of size 10 be an unusually large number?f.
