QUESTION 22 Calculate the risk ratio for this study. Round to the nearest hundredth. A hypothetical study was undertaken among 600 ADHD-free children in South Carolina. The purpose of the study was to examine the effects of increased screen time during childhood on the subsequent diagnosis of ADHD by young adulthood. The children's screen time was assessed by a questionnaire, and the children were followed for 10 years. The following data were obtained from the study: Screen Time 4 or More Hours per Day Less than 4 Hours per Day Total ADHD 125 175 300 No ADHD 135 165 300 Total 260 340 600

QUESTION 2 Using the same anti-venom study, answer the following questions. Researchers wanted to know the effectiveness of a new anti-venom. A study was conducted on 150 children who had nonlethal scorpion stings. The ages of the children ranged from 6 months to 18 years old. Each child was randomly assigned to receive a shot of the anti-venom or a placebo shot. Researchers recorded whether or not their condition improved over the next four hours. a. Identify the population for the study.b. Identify the sample for the study.c. Was this an observational study or a controlled experiment? Explain how you know.d. Assuming the rest of the study was well-designed, use the percentages you calculated in question 1 and the type of study conducted to discuss whether it would be reasonable to conclude that the new anti-venom is effective at treating nonlethal scorpion stings in children.

Question 1 1. Which IAT data set are you working with? 2. 3. Use StatCrunch and your unique IAT sample to estimate the mean age for the population of IAT participants at the 90% confidence level. Copy the contents of your StatCrunch output window and paste them into your response. (No need to type anything here - just copy and paste the contents of your StatCrunch output window.) Are conditions met to estimate the mean age for the population of IAT participants? (Be sure to support your answer as demonstrated throughout Unit 8.) 4. State the confidence interval, and then interpret the confidence interval in context. 5. What is the margin of error (MOE)? 6. Which would be more accurate, the 90% confidence interval you found or an 85% confidence interval? Briefly explain. Which would be more precise? Briefly explain. One sample T confidence interval: μ: Mean of variable 90% confidence interval results: Variable Sample(IAT-Weight-Score) Sample Mean Std. Err. DF L. Limit U. Limit…
. Do patients with gastrointestinal issues experience more psychological distress than the general population? The DASS-21 questionnaire is a validated measure of depression, anxiety, and stress. For the general population, the mean for anxiety is µ = 4.2. Anxiety levels are calculated based on self-reported answers to questions on a scale from 0 through 42, with lower scores indicating lower anxiety. Participants with gastrointestinal issues (specifically inflammatory bowel disease, IBD) completed the DASS-21. Use the data presented below to determine whether having gastrointestinal issues like IBD significantly increases risk for anxiety. Test whether or not the performance of this sample is significantly higher than the normal population using the proper t-test. Here are the data: Anxiety scores: 12, 15, 10, 8, 10, 5, 10, 13, 4, 6 ANALYSES AND UNGRADED OPTIONAL GUIDING QUESTIONS: 1a. Identify the Indep.Variable:__ Dep.Variable:__ Is it the Hypothesis…
You conducted a study to assess the effect of smoking on systolic blood pressure. The results showed that there was a significant association between the two variables, with an odds ratio of 1.5. Explain this finding to someone who has no background in epidemiologic research.
Discuss the basic epidemiology measures used in the Colorado uranium miners study. Specifically what measure of risk was used? How was risk calculated? (Hint: Consider a 2 by 2 table to display the data). Do you agree with the authors' conclusions? What would you infer from the data? Why?
The phrase “Correlation does not equal causation” means: Question 30 options: there is no guarantee that a cause-and-effect relationship exists between two variables that are correlated. there is only a 30% chance that a cause-and-effect relationship exists between two variables. a cause-and-effect relationship only certainly exists when data are gathered in a specific way. a cause-and-effect relationship can only exist with ratio-level variables.
The average income of a large sample of households is $63,000 and the s.d. is $7,000. Assume that the data is approximately bell-shaped. What percent of these households have incomes between $42,000 and $77,000? Don’t forget to properly justify your answer using the empirical rule.

Question 7: Weight loss: In a study to determine whether counseling could help people lose weight, a sample of people experienced a group-based behavioral intervention, which involved weekly meetings with a trained interventionist for a period of six months. The following data are the numbers of pounds lost for 14 people. Assume the population is approximately normal. Perform a hypothesis test to determine whether the mean weight loss is greater than 13 pounds.
