For many years businesses have struggled with the rising cost of health care. But recently, the increases have slowed due to less inflation in health care prices and employees paying for a larger portion of health care benefits. A recent Mercer survey showed that 65% of U.S. employers were likely to require higher employee contributions for health care coverage in 2009. Suppose the survey was based on a sample of 633 companies. Compute the margin of error and a 90%...

The Cost of the U.S. Health Care System Describe three different reimbursement methods (e.g., capitation, fee-for-service [FFS], pay-for-performance [P4P], value-based, episode of care, prospective reimbursement, diagnosis related group [DRG], patient-centered medical home [PCMH]). Explain why you think one of the reimbursement methods you discussed is more effective at reducing health care costs overall while still ensuring the delivery of quality care. Describe the use of two technological advancements (e.g., electronic medical record [EMRs], electronic health records [EHRs], medical research, improved...

Birth weight and gestational age. The Child Health and Development Studies considered pregnancies among women in the San Francisco East Bay area. Researchers took a random sample of 50 pregnancies and used statistical software to construct a linear regression model to predict a baby's birth weight in ounces using the gestation age (the number of days the mother was pregnant). A portion of the computer output and the scatter plot is shown below. Round all calculated results to four decimal...

Question 4 (0.5 points) Sleep apnea is a disorder in which there are pauses in breathing during sleep. People with this condition must wake up frequently to breathe. In a sample of 339 people aged 65 and over, 112 of them had sleep apnea. What is the lower bound for the 90% confidence interval for the proportion of those aged 65 and over who have sleep apnea. Round to three decimal places (for example: 0.419). Write only a number as...

4. Meta-analysis-Mean risk ratio Aa Aa To help reduce the risk of alcohol-related health problems in heavy drinkers, many health care institutions offer therapy sessions known as brief interventions. These are a small number (1-4) of short, motivational counseling sessions (usually under 30 minutes each), which include education and advice about the dangers of heavy drinking A meta-analytical review conducted in 2002 of 56 clinical trials comparing outcomes of brief interventions with control conditions found positive evidence for brief intervention,...

In what follows use any of the following tests/procedures: Regression, confidence intervals, one-sided t-test, or two-sided t-test. All the procedures should be done with 5% P-value or 95% confidence interval. Open Weight_vs_IQ data. SETUP: Common sense dictates that a person’s IQ and Weight should not be related. However, one never knows until one examines the data. Given the data (IQ and weight for 29 students) your job is to check if the common sense assumption is reasonable or maybe it...
