Below is an abstract from the paper, "BEYOND JOB LOCK: IMPACTS OF PUBLIC HEALTH INSURANCE ON OCCUPATIONAL AND INDUSTRIAL MOBILITY," by Ammar Farooq Adriana Kugler. We examine whether greater Medicaid generosity encourages mobility towards riskier but better jobs in higher paid occupations and industries. We use Current Population Survey Data and exploit variation in Medicaid thresholds across states and over time through the 1990s and 2000s. We find that moving from a state in the 10th to the 90th percentile in terms of Medicaid income thresholds increases occupational and industrial mobility by 7.6% and 7.8%. We also find that higher income Medicaid thresholds increase mobility towards occupations and industries with greater wage spreads and higher separation probabilities, but with higher wages and higher educational requirements. Given this description, you can assume that the likely identification strategy used is _____. Furthermore, the findings found in this paper are ____…
(A) Socially conscious investors screen out stocks of alcohol and tobacco makers, firms with poor environmental records, and companies with poor labor practices. Some examples of "good," socially conscious companies are Johnson and Johnson, Dell Computers, Bank of America, and Home Depot. The question is, are such stocks overpriced? One measure of value is the P/E, or price-to-earnings ratio. High P/E ratios may indicate a stock is overpriced. For the S&P Stock Index of all major stocks, the mean P/E ratio is ? = 19.4. A random sample of 36 "socially conscious" stocks gave a P/E ratio sample mean of x = 17.6, with sample standard deviation s = 5.6. Does this indicate that the mean P/E ratio of all socially conscious stocks is different (either way) from the mean P/E ratio of the S&P Stock Index? Use ? = 0.05 i-What is the value of the sample test statistic? (Round your answer to three decimal places.) (B)Let x be a random variable that represents red blood cell count (RBC) in…
A mining company finds that daily lost-work injuries averages to 1.2. If the local union contract has a clause requiring that the mine be shut down as soon as three workers incur lost-work injuries, on what percentage of the days will the mine be operational throughout the day?
In an article in Accounting and Business Research, Beattie and Jones investigate the use and abuse of graphic presentations in the annual reports of United Kingdom firms. The authors found that 65 percent of the sampled companies graph at least one key financial variable, but that 30 percent of the graphics are materially distorted (nonzero vertical axis, exaggerated trend, or the like). Results for U.S. firms have been found to be similar. (a) Suppose that in a random sample of 466 graphics from the annual reports of United Kingdom firms, 142 of the graphics are found to be distorted. Find a point estimate of and a 95 percent confidence interval for the proportion of all U.K. annual report graphics that are distorted. (Round your answers to 4 decimal places.)

Results for U.S. firms have been found to be similar. (a) Suppose that in a random sample of 451 graphics from the annual reports of United Kingdom firms, 146 of the graphics are found to be distorted. Find a point estimate of and a 95 percent confidence interval for the proportion of all U.K. annual report graphics that are distorted. (Round your answers to 4 decimal places.) (b) Based on this interval, can we be 95 percent confident that more than 25 percent of all graphics appearing in the annual reports of U.K. firms are distorted? Does this suggest that auditors should understand proper…
In a Denver community, 50 cases of diabetes were reported among 15-19 years old out of a total population of 46,000 between September 1 to December 31, 2016. Ten percent (4,600) of the population were between 15-19 years old on April 1, 2016 and the size and age distribution of the population has remained constant. An investigation of the cases in the 15-19-year age group revealed that 22 of the reported cases were contracted prior to September 1. In addition, another 18 cases developed in April and May but were clinically resolved before September 1. What was the cumulative incidence rate of disease in 15-19 year olds per 1,000 population in this Denver community during the period September 1 to December 31, 2016?
A consumer magazine wants to figure out which of two major airlines lost a higher proportion of luggage on international flights. The magazine surveyed Standard Air (population 1) and Down Under airlines (population 2). Standard Air lost 45 out of 600 bags. Down Under airlines lost 30 of 500 bags. Does Standard Air have a higher population proportion of lost bags on international flights? Which of the following is the correct competing hypotheses?
