Got 3 question similar to what i postedsend draft in 12 hrs time, n need to draft quetsiosn

Mathematics in the Real-World Here is a list of many such application concepts that were discussed throughout the book: Global melting (page 70) Save money and save the earth (page 99) Federal budget (page 173) How numbers can deceive polygraph, mammogram, and more (page 178) Measuring your money by understanding tax, interests, investments, loans, budget, etc. (Chapter 4) Should you believe a statistical study (Chapter 5B) Graphics in the media (Chapter 5D) Correlation and causality (Chapter 5E) Is polling reliable (page 414) Exponential and logarithmic scales and their use in understanding acidification of lakes and oceans and effect of exponential population rise (Chapter 8) Ocean acidification (page 526) Climate modeling (page 534) Mathematics of politics (Chapter 12) For this journal entry, choose any two application problems from the above list and answer the following questions. What are the two topics that you have chosen? Why did you choose the topics? How will you use the applications in your own life? Be very specific. How can you use the applications in your own community? For example, if you believe in climate change and you find that your senator, congressperson, or members of your town council do not believe in climate change, how can you use your knowledge to change their beliefs? This is just an example. You can use this or your own examples and ideas to discuss how you can use your applications for the betterment of the society and the country. Did you know about all these math applications before you took the class? How has your perspective about math changed after taking this class? Were you afraid of math before taking this class? Are you still afraid? Why or why not? Reflect on your journey through the 5 weeks of this class.  

Module 8 - Treating Depression Lab Part 2 (discussion 2) - mod 8 group 1From 2020SU-MATH-160-177422 unread replies.22 replies.Learn by DoingIn this activity, you will investigate the first question related to the study described below.Some features of this activity may not work well on a cell phone or tablet. We highly recommend that you complete this activity on a computer.Here are the directions and grading rubric for the Learn by Doing discussion board exercises. A list of StatCrunch directions is provided at the bottom of this page.ContextClinical depression is a recurrent illness requiring treatment and often hospitalization. Nearly 50% of people who have an episode of major depression will have a recurrence within 2-3 years. Being able to prevent the recurrence of depression in people who are at risk for the disease would go a long way to alleviate the pain and suffering of patients.During the 1980's the federal government, through the National Institutes of Health (NIH), sponsored a large clinical trial to evaluate two drugs for depression. There were 3 treatment groups. Patients received either Imipramine (Imip), Lithium (Li), or a Placebo (Pl). Researchers randomly assigned patients to one of the 3 treatment groups and followed them for 2-4 years to track any recurrences of depression.(Prien et al., Archives of General Psychiatry, 1984).VariablesHospt: Which hospital the patient was from: Labeled 1, 2, 3, 5 or 6Treat: 0=Lithium; 1=Imipramine; 2=PlaceboOutcome: 0=Success 1=Failure (recurrence of depression)Time: Number of weeks until a recurrence (if outcome=1) or until study ended (if outcome=0)AcuteT: How long the patient was depressed before the start of the current study, measured in daysAge: Age in yearsGender: 1=Female 2=MaleDataIf you have not done so already, download the depression datafile (as always, if a login box opens, just close it and then download the file). Then upload the file in StatCrunch. PromptWe will analyze the data to answer the second research question: Which of the drugs (if either) delayed the recurrence of depression longer relative to the placebo? In the previous lab-preparation activity, we identified Treat as the explanatory variable and Time as the response variable. We also determined that we will analyze the data using side-by-side boxplots and descriptive statistics (i.e. 5-number summaries since the graphs are boxplots).Make graphs and tables.Use StatCrunch to produce side-by-side boxplots. (directions)Embed your graphs with your initial post. Use StatCrunch to produce the descriptive statistics (a table containing the 5-number summaries for each comparison group). (directions)Copy and paste the StatCrunch output table into your initial post. Analyze the data: Compare the distributions for the treatment groups as demonstrated in Unit 2. For example, compare medians and intervals of typical values. Describe the shape and any outliers. Be sure to write your comparisons so the reader can understand the context of the numbers. For example, don't just say the median is 30; instead, say something like this: on average patients taking the placebo relapsed in 30 days (Q2=30 days).Draw a conclusion: What can we conclude from your analysis? Did one drug successfully delay a relapse of depression better than the others? What evidence supports your conclusion?Summarize your conclusions in response to both research questions: In this lab you compared three treatments using two different variables: (Parts 1 & 2) whether or not a relapse into depression occurred and (Parts 3 & 4) if a relapse occurred, the time it took to occur. What can you conclude in light of both analyses? Is one treatment better than the other? How does the data support your conclusion?List of StatCrunch DirectionsEach link will open in a new window.
