On December 17, 2010, the Wilmington, North Carolina StarNews carried an Associated Press report headlined "13 million get unexpected tax bill from Obama tax credit". The report said that The Internal Revenue Service reported that the average tax refund was $2,892 in the 2010 filing season, up from $2,663 in 2009. However, the number of refunds dropped by 3.5 percent to 93.3 million. What was the percentage increase in the average tax refund from 2009 to 2010? $2,892 - $2,663= 229 ÷ $2,663= 0.08599324% was the percentage increase from 2009 to 2010. How many refunds were there in 2009 and in 2010? (Use the information given in the problem to find your answer.) c. The number of refunds decreased while the average refund increased, so you need some arithmetic to decide how the total dollar amount refunded changed from 2009 to 2010. Find that change in both absolute and percentage terms

Internal auditors are often used to review an organization’s financial statements, such as balance sheets, income statements, and cash flow statements, prior to public filings. Auditors seek to verify that the financial statements accurately represent the financial position of the organization and that the statements follow accepted accounting principles. Many errors that are discovered by auditors are minor errors that are easily corrected. However, some errors are serious and require substantial time to rectify. Suppose that the financial statements of 567 public companies are audited. The following table contains the number of errors discovered during the internal audit of each of 567 these public companies that were classified as “serious.” Number of Serious Errors (x) Frequency 0 237 1 93 2 52 3 40 4 80 5 56 6 7 Number of Serious Errors (x) Frequency Probability f(x) 0 237 1 93 2 52 3 40 4 80…

You may need to use the appropriate appendix table or technology to answer this question. Advertisers contract with internet service providers and search engines to place ads on websites. They pay a fee based on the number of potential customers who click on their ad. Unforțunately, click fraud-the practice of someone clicking on an ad solely for the purpose of driving up advertising revenue–has become a problem. Businessweek reports that 4C percent of advertisers claim they have been a victim of click fraud. Suppose a simple random sample of 390 advertisers will be taken to learn more about how they are affected by this practice. (Round your answers to four decimal places.) (a) What is the probability that the sample proportion will be within ±0.04 of the population proportion experiencing click fraud? (b) What is the probability that the sample proportion will be greater than 0.45?
