A company receives complaints about their product bending and needs to determine how many faulty products are going undetected. The company uses a scanning device that places a mark on each defective product that it detects on the production line. However not all defective products are detected by the scanner, and sometimes it marks a product which is not defective. When a product is not defective, the scanner marks it 5% of the time. When a product is defective, the scanner marks it 98% of the time. The quality control department reports that 4% of all products are defective. Which option will calculate the probability that the product is marked?

In 2010, the U.S. Congress passed the historic health care reform bill that will provide some type of coverage for the 32 million Americans currently without health care insurance. Just how widespread is the lack of medical coverage? The media claim that the segments of the population most at risk for disease and thus needing healthcare are women, children, the elderly and the poor. The following tables were generated from the U.S. Census Bureau, Current Population Survey, Annual Social and Economic Supplement (2011). The tables report the number of uninsured (in thousands) by sex, by age, and by household income Is being insured or not dependent on the income groups identified in the analysis? Fill in the degrees of freedom and p-value in the output below and draw a clear conclusion indicating which income-groups are more at risk of not being insured if there is a significant relationship.
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?

Several years ago, two companies merged. One of the concerns after the merger was the increasing burden of retirement expenditures. An effort was made to encourage employees to participate in the 401(k) accounts. Nationwide, 62% of eligible workers participated in these accounts. The accompanying data table contains responses of 30 employees of the company when asked if they were currently participating in a 401(k) account. Complete parts a through d. Click the icon to view the data table. a. Determine the sample proportion of company workers who participate in 401(k) accounts. The sample proportion is (Round to three decimal places as needed.) b. Determine the sampling error if in reality the company workers have the same proportion of participants in 401(k) accounts as does the rest of the nation. The error is. (Round to three decimal places as needed.) c. Determine the probability that a sample proportion at least as large as that obtained in the sample would be obtained if the…
