For developing countries in Africa and the Americas, let p₁ and p₂ be the respective proportions of babies with a low birth weight (below 2500 grams). A random sample of n₁ = 2000 African women yielded y₁ = 750 with nutritional anemia anda random sample of n₂ = 2000 women from the Americas yielded y₂ = 650 women with nutritional anemia. We shall test H₀: p₁ = p₂ against the alternative hypothesis H₁: p₁ > p₂ at α = 0.05.

Suppose the incidence rate of myocardial infarction (MI) was 10 per 1000 among 45- to 54-year-old men in 1990. To look at changes in incidence over time, 3000 men in this age group were followed for 1 year starting in 2000. 40 new cases of MI were found. Using both rejection region and p-value approach with α = .05, test the hypothesis that incidence rates of MI changed from 1990 to 2000.

Suppose a system uses a Public-Key Infrastructure with a Certificate Revocation List. A device in that system is asked to verify a certificate but cannot access the Certificate Revocation List database because of a denial of service attack What are the possible courses of action for the device, and what are the advantages and disadvantages of each course of action?

Choose one type of complementary or alternative (CAM) therapy and discuss its benefits in preventing and treating disease. Discuss how the use of this CAM therapy can reduce the need for medications. Research this therapy on ProQuest or another scholarly database. What does the research demonstrate regarding its efficacy?

Evaluate three emerging issues that relate to the implementation of IT systems and the related impact to the fraud environment. Recommend a risk mitigation strategy associated with installing a new database system, and determine the impact of designing an effective internal control audit plan to determine whether those risks have been identified.

(a) Construct the P-V graph for the Carnot cycle operating between 700 and 200 ^oC if isothermal expansion of water vapor occurs between 1 and 8 L/mol. Determine the relevant quantities of heat, work, energy and entropy. Compare the results obtained using the IGL and the NIST database.

Consider the following actions taken by transaction T1 on database objects X and Y:

R(X), W(X), R(Y), W(Y)

Give an example of another transaction T2 that, if run concurrently to transaction T1 without some form of concurrency control, could interfere with T1.
