(1 point) In 2002 the Supreme Court ruled that schools could require random drug tests of students participating in competitive after-school activities such as athletics. Does drug testing reduce use of illegal drugs? A study compared two similar high schools in Oregon. Wahtonka High School tested athletes at random and Warrenton High School did not. In a confidential survey, 4 of 131 athletes at Wahtonka and 20 of 114 athletes at Warrenton said they were using drugs. Regard these athletes as SRSs from the populations of athletes at similar schools with and without drug testing. (a) You should not use the large-sample confidence interval. Why not? (b) The plus four method adds two observations, a success and a failure, to each sample. What are the sample sizes and the numbers of drug users after you do this? Wahtonka sample size: Wahtonka drug users: Warrenton sample size: Warrenton drug users: (c) Give the plus four 90% confidence interval for the difference between the proportion of athletes using drugs at schools with and without testing.

Sarbanes-Oxley Act (SOX) was introduced in 2002 by the United States Congress to fight corporate financial statement fraud. Since its implementation, there have been questions about its effectiveness. After reading the Dutillieux, Francis, and Willekens (2016) article, ”The Spillover of SOX on Earnings Quality in Non-US Jurisdictions (Links to an external site.)” discuss what earnings quality is and how the concern over that quality may have led to the enactment of SOX. How does SOX (a piece of U.S. Legislation) impact companies in other countries?

random sample of congressional campaigns from 2002.
FUNDS: Total money raised for the campaign, in thousands of dollars DSIZE: Area of the candidate’s congressional district, in square miles FUNDCARD: 1 = campaign website allowed credit card donations, 0 = campaign website did not allow credit card donations We wanted to know if amount of money raised for a campaign depends on the how large the district is and whether the campaign accepted credit card donations on its website.
We ran a regression. Regression results Dependent variable: FUNDS Adjusted R Square: .154 Constant (a): 673.642 B coefficient FUNDCARD: 1908.063 (p = .000), Standardized Beta .361 B coefficient DSIZE: .007 (p = .019), Standardized Beta .183
Write the equation for the regression, using the format yhat = a + bx + bx, filling in the numbers for a and b, and the names of the variables in place of y and x. 9.
Write one sentence interpreting the b coefficient for FUNDCARD.
Write one sentence identifying and interpreting the p value for the b coefficient for FUNDCARD. Refer to the null hypothesis and show that you know what it means for this specific example.

Smith Family
Assume the Smith family of Philadelphia, Pennslyvania purchased their home in 2002 for $80,000. Since then, comparable homes in their neighborhood have most recently sold for $200,000. The cost to replace the home would be $180,000. It is estimated that the house is one-third depreciated. The Smith’s have a $175,000 (face amount coverage A) Homeowners policy in force, similar to the policy shown in the Appendix. Answer the following questions as if each question were a separate event.
1) How much will the Smith’s collect for a total covered fire loss under coverage A?
2) How much will be collected for a $20,000 partial loss under coverage A
3) What would be your answers to questions 1 and 2 above if the Smith’s had only $80,000 of insurance of Coverage A?

Does drug testing reduce use of illegal drugs? A study compared two similar high schools in Oregon. Wahtonka High School tested athletes at random and Warrenton High School did not.

Regard these athletes as SRSs from the populations of athletes at similar schools with and without drug testing.
(a) You should not use the large-sample confidence interval. Why
not?
Choose a reason. The sample sizes are too small. The sample sizes
are not identical. The sample proportions are too small. At least
one sample has too few failures. At least one sample has too few
successes.
(b) The plus four method adds two observations, a success and a failure, to each sample. What are the sample sizes and the numbers of drug users after you do this?
Wahtonka sample size: Wahtonka
drug users:
Warrenton sample size: Warrenton drug

(c) Give the plus four 99.9% confidence interval for the
difference between the proportion of athletes using drugs at
schools with and without testing.

The 2002 SOX Act required integrated audits for all public companies with immediate implementation by larger accelerated-filers. The 2010 Dodd-Frank Act modified section 404 of the SOX Act to exempt certain smaller companies (non-accelerated-filers) from having external audits of their ICFR.
Given the importance and function of internal controls and known fraudulent activities, do you agree with this modification that eliminated the need for these smaller public companies from having auditor’s express an opinion on their ICFR? Explain your answer.
Though recommended, there is no requirement for private and not-for-profit companies to have external auditors audit their ICFR. Explain whether you feel these organizations should have their ICFR audited by external auditors.
