COPD) is quite common with over 3 million cases per year in the United States alone. This disease has several symptoms (such as shortness of breath) and can increase the risk of mortality, especially among older individuals. There is growing evidence that poor indoor air quality can trigger symptoms and increase the likelihood of being diagnosed. You are part of a research team that is assessing the effectiveness of both a new indoor filtration system as well as a new drug in the hope of reducing symptoms within diagnosed populations (specifically shortness of breath and wheezing). There are two explanatory factors (1) a novel air filtration system with two levels (they have the new system, or they do not) and (2) new drug with three levels (high dose, low dose, and placebo). You recruit 60 individuals and randomly assign them to a treatment. a. What type of study is this (1-2 sentences)? b. What is the explanatory and response variables? c. How many treatments combinations are there? How many individuals within each treatment? This should be shown visually (either a schematic or a table) d. Write 2-3 sentences explaining.question 1c e. Explain a strategy to recruit individuals for this study. You should be thinking about recruitment strategy, getting a representative sample, bias, demographics, etc (3-5 sentences)

Transcribed Image Text:Chronic Obstructive Pulmonary Disease (COPD) is quite common with over 3 million cases per year in the
United States alone. This disease has several symptoms (such as shortness of breath) and can increase the
risk of mortality, especially among older individuals. There is growing evidence that poor indoor air quality
can trigger symptoms and increase the likelihood of being diagnosed. You are part of a research team that

Expert Solution
Step 1
Chronic Obstructive Pulmonary disease symptoms are shortness of breath and risk of mortality among elderly individuals.
This disease is caused due to poor indoor air quality and hence, the symptoms are triggered.
Diagnosing the systems can assess the effectiveness of indoor filtration and novel drug creation for reducing the symptoms.
| novel air filtration | No system |
| levels | New System |
| new drug | High dose |
| levels | low dose |
| placebo |
