A Canadian longitudinal study1 examines whether giving antibiotics in infancy increases the likelihood that the child will be overweight later in life. Prescription records were examined to determine whether or not antibiotics were prescribed during the first year of a child's life, and each child was classified as overweight or not at age 12. The researchers compared the proportion overweight in each group. The study concludes that: "Infants receiving antibiotics in the first year of life were more likely to be overweight later in childhood compared with those who were unexposed (32.4% versus 18.2% at age 12, P=0.002)." (h) What is the value of the sample statistic?Value:
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 ____…
The Behavioral Risk Factor Surveillance System (BRFSS) is an annual telephone survey designed to identify risk factors in the adult population and report emerging health trends. The following table displays the distribution of health status of respondents to this survey (excellent, very good, good, fair, poor) and whether or not they have health insurance. Excellent Very good Good Fair Poor Total No health coverage 459 727 854 385 99 2524 Health coverage 4198 6245 4821 1634 578 17476 Total 4657 6972 5675 2019 667 20000 (a) Why is being in excellent health and having health coverage not mutally exclusive? Please leave a detailed answer and how you found out. (b) If we draw one individual at random, what is the probability that the respondent has excellent health or doesn't have health coverage? Please leave a detailed answer on how you found that answer. (c) What is the probability that a randomly chosen individual has excellent health given that he has health…
