A certain HMO is attempting to show the benefits of managed care to an insurance company. The HMO believes that certain types of doctors are more cost-effective than others. One theory is that certification level is an important factor in measuring the cost-effectiveness of physicians. To investigate this, the HMO obtained independent random samples of 27 physicians from each of the three certification levels-Board certified (C): Uncertified, board eligible (E); and Uncertified, board ineligible (1)- and recorded the total per member per month charges for each (a total of 81 physicians). How many factors are present in this study? 0000 81 27 3 01
A study published in 2007 by Christopher Johnson, professor of music education and music therapy at the University of Kansas, revealed that students in elementary schools who took private music lessons scored around 20 percent higher in math scores on standardized tests, compared to students who did not take private music lessons. Is this a randomized experiment or an observational study? a) Randomized experiment, since researchers gave students standardized tests. b) Observational study, since whether the student took private music lessons was not randomly assigned. c) Observational study, since math scores were not randomly assigned. d) Observational study, since this was not a random sample.
According to a Pew Research Center study, in May 2011, 33% of all American adults had a smart phone (one which the user can use to read email and surf the Internet). A communications professor at a university believes this percentage is higher among community college students. She selects 320 community college students at random and finds that 135 of them have a smart phone. In testing the hypotheses: Ho: p = 0.33 versus Ha: p > 0.33 Do the hypothesis test. Use a level of significance of a = 0.05; Use the unrounded values in Excel to find the answers for #3 and #4. 1. This is an example of a hypothesis test. 2. Find the standard error. 3. Find the z value. 4. Find the p-value. 5. The communication professor should the null hypothesis.
In randomized, double-blind clinical trials of a new vaccine, children were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second dose, 125 of 746 subjects in the experimental group (group 1) experienced fever as a side effect. After the second dose, 82 of 627 of the subjects in the control group (group 2) experienced fever as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced fever as a side effect than subjects in group 2 at the a= 0.01 level of significance? Find the test statistic for this hypothesis test. (Round to two decimal places as needed.)
Researchers studied the behavior of birds that were searching for seeds and insects in an Oregon forest. In this forest, 54% of the trees were Douglas firs, 40% were ponderosa pines, and 6% were other types of trees. At a randomly selected time during the day, the researchers observed 156 red-breasted nuthatches: 70 were in Douglas firs, 79 in ponderosa pines, and 7 in other types of trees. Do these data provide convincing evidence that nuthatches prefer particular types of trees when they’re searching for seeds and insects?
A manufacturer of laptop computers claims that only 1% of their computers are defective. In a sample of 600 computers, it was found that 3% were defective. If the proportion of defectives were really only 1%, there would be than 1 chance in 1000 of getting such a large proportion of defective laptops in the sample. Is there statistically significant evidence against the manufacturer's claim? Why or Why not?

A study was conducted in Thailand to study the association between Vitamin A deficiency and death among children with measles. A summary of their data is provided below. Which of the following statements is true? Died Did not die Have Vitamin deficiency 20 20 Do not have vitamin deficiency 25 100 Those without vitamin D deficiency are more likely to die than those with Vitamin D deficiency There is no association between Vitamin D deficiency and death Those with Vitamin D deficiency are more likely to die than those without Vitamin D deficiency None of these answers are co
Recent research findings have shown that older people who practice ballroom dancing are 77% less likely to experience dementia compared to those senior citizens who did not dance. Drawing on this surprising result, Dr. Anders Ericsson thinks that ballroom dancing may also reduce one's level of stress to a greater extent than conventional exercise routines. To validate his claim Dr. Ericsson has randomly selected 100 senior citizens who were then randomly split into two groups, with the first group practicing ballroom dancing 3 times a week and the second group undergoing a conventional exercise regiment 3 times a week also. The measures of stress were assessed for each participant after the study was completed. What is the most appropriate set of hypotheses for this study? HO: μD- 0; H1: μD 0 HO: µD = 0; H1: µD > 0 %3D HO: udance - pexercise = 0; H1: µdance - pexercise <0
Aarskog syndrome is a rare genetic condition affecting approximately 1/25,000 people. Researchers have found FGD1 gene mutations in approximately 22% of individuals with Aarskog syndrome. A study looking to establish causality reported an odds ratio for Aarskog syndrome of 2.24 (95% CI 1.2 to 3.45), comparing people with FGD1 mutations to those without. a) Provide a correct interpretation of this odds ratio b) Provide a plausible value for the risk ratio for Aarskog syndrome, comparing people with FGD1 mutations to those without. Why did you choose this value?
