STA3215CBE Rasmussen Critical Regions & P Values Population Parameters Paper
CompetencyFormulate and evaluate hypothesis tests for population parameters
based on sample statistics using both Critical Regions and P-Values, and
be able to state results in a non-technical way that can be understood
by consumers of the data instead of statisticians.Student Profile
You are a statistician working for a drug company. A few new
scientists have been hired by your company. They are experts in
pharmacology, but are not experts in doing statistical studies, so you
will explain to them how statistical studies are done when testing two
samples for the effectiveness of a new drug. The two samples can be
dependent or independent, and you will explain the difference.
Concept being Studied
Your focus is on hypothesis tests and confidence intervals for two
populations using two samples, some of which are independent and some of
which are dependent. These concepts are an extension of hypothesis
testing and confidence intervals which use statistics from one sample to
make conclusions about population parameters.What to SubmitYour research and analysis should be presented on the Word document provided. All calculations should be provided on a separate Excel workbook that should be submitted to your boss as well.

What are the means and standard deviations, statistics homework help
Exercise 16 1. What do degrees of freedom ( df ) mean? Canbulat et al. (2015) did not provide the df s in their study. Why is it important to know the df for a t ratio? Using the df formula, calculate the df for this study. 2. What are the means and standard deviations ( SD s) for age for the Buzzy intervention and control groups? What statistical analysis is conducted to determine the difference in means for age for the two groups? Was this an appropriate analysis technique? Provide a rationale for your answer. 3. What are the t value and p value for age? What do these results mean? 4. What are the assumptions for conducting the independent samples t -test? 5. Are the groups in this study independent or dependent? Provide a rationale for your answer. 6. What is the null hypothesis for procedural self-reported pain measured with the Wong Baker Faces Scale (WBFS) for the two groups? Was this null hypothesis accepted or rejected in this study? Provide a rationale for your answer. 7. Should a Bonferroni procedure be conducted in this study? Provide a rationale for your answer. 8. What variable has a result of t = − 6.135, p = 0.000? What does the result mean? 9. In your opinion, is it an expected or unexpected finding that both t values on Table 2 were found to be statistically significant. Provide a rationale for your answer. 10. Describe one potential clinical benefit for pediatric patients to receive the Buzzy intervention that combined cold and vibration during IV insertion. Exercise 17 1. What are the assumptions for conducting a paired or dependent samples t -test in a study? Which of these assumptions do you think were met by the Lindseth et al. (2014) study? 2. In the introduction, Lindseth et al. (2014) described a “2-week washout between diets.” What does this mean? Why is this important? 3. What is the paired t -test value for mood (irritability) between the participants ’ consumption of high- versus low-aspartame diets? Is this result statistically significant? Provide a rationale for your answer. 4. State the null hypothesis for mood (irritability) that was tested in this study. Was this hypothesis accepted or rejected? Provide a rationale for your answer. 5. Which t value in Table 2 represents the greatest relative or standardized difference between the high- and low-aspartame diets? Is this t value statistically signifiant? Provide a rationale for your answer. 6. Discuss why the larger t values are more likely to be statistically significant. 7. Discuss the meaning of the results regarding depression for this study. What is the clinical importance of this result? 8. What is the smallest, paired t -test value in Table 2 ? Why do you think the smaller t values are not statistically significant? 9. Discuss the clinical importance of these study results about the consumption of aspartame. Document your answer with a relevant source. 10. Are these study findings related to the consumption of high- and low-aspartame diets ready for implementation in practice? Provide a rationale for your answer.

Financial Homework
Directions:
Answer the following questions on a separate document. Explain how you
reached the answer or show your work if a mathematical calculation is
needed, or both. Submit your assignment using the assignment link above.
This homework assignment is worth 20 points. Responses should be at least 75 words for each question. 1) Would you characterize the U.S. dollar as a freely floating or dirty float system? What characteristics support your answer? 2) What is direct central bank intervention in the currency markets and provide an example of this from the last 50 years. 3)
Assume that Canada suddenly experiences high inflation. How might this
affect the value of the Canadian dollar according to the purchasing
power parity (PPP) theory? 4)
Australia's central bank decides to increase the value of the
Australian dollar against the Japanese yen. How might it use direct
intervention to do this? 5) Assume the following information: • Mexican one-year interest rate = 15% • U.S. one-year interest rate = 11% If
interest rate parity exists, what would be the forward premium or
discount on the Mexican peso’s forward rate? Would covered interest
arbitrage be more profitable to U.S. investors than investing at home?
Explain. 6) Create a balance sheet for a typical bank, showing its main liabilities (sources of funds) and assets (uses of funds). 7)
The Federal Reserve has increasingly favored the use of Repurchase
Agreements as part of its open market operations. Briefly describe
these and why the Fed or banks prefer to use them. 8)
Banks engage in proprietary trading as part of their operations.
Briefly speculate on why they now must adhere to much more stringent
trading activity as a result of the 2008-09 financial crises. 9) Briefly describe two off-balance sheet activities and why banks favor the use of these. 10)
If you were the CEO of a US bank, would you consider establishing a
foreign branch? What might be a concern related to doing so?

Please download the required CSV data file here:https://drive.google.com/file/d/1R63J3Z2LtnIsdnhqdBNt-4lxEzTOxpmI/view?usp=sharing (Links to an external site.)This assignment will focus on using some of the techniques we have seen over the past three weeks for manipulating data in R. For this assignment we will be working with a dataset consisting of demographics together with weekly religious service attendance for 5000 individuals. Most of the variable names are self-explanatory, but the “Weekly Attendance” column shows a value of “1” for those who report attending religious services weekly and “0” for those who don’t. You will read this file into R and answer a few questions that will require you to apply data transforms for finding the answer.Important Formatting Instructions: Please round all answers to the nearest whole number. There should be no decimals or commas, only integers. Here some examples of what to do (good examples) and what NOT to do (bad examples):Good Examples (enter examples like these): 5, 2, 22, 11, 128, 228000Bad Examples (don’t do this!): 5.31, 2.0, 22.000, 11.88231, 128.0, 228,000INTEGRITY STATEMENTYou must work on this entirely alone without consulting with any other student. You may certainly use your notes and any class materials as well as outside R resources, but you may NOT ask others for help or seek the answers on the Internet or from any other source. This must be entirely your own work. Additionally, you may NOT discuss these answers or in any way make them public. The Honor Code is in full effect!HOW TO SUBMITUse R to answer the questions below. It is recommended to work the answers out first, then log into the website below to enter your answers. You will need to enter them all in one sitting. Please MAKE SURE to follow the formatting instructions so you don’t needlessly lose points.Once you are ready, you may log on with your NetID and enter your answers HERE (Links to an external site.)QUESTIONS1.

How many married females are in this dataset?6. How many unmarried males attend services weekly in this dataset?7. What is the median income of those who attend services weekly?8. What is the median income of those who DO NOT attend services weekly?For the next 3 questions, add a new column called “HigherEd” that provides a label based on years of education according to the following rules:Educ < 12: “None”12 <= Educ < 16: “HighSchool”16 <= Educ < 17: “College”17 <= Educ < 19: “Masters”Educ >= 19: “Doctorate”9.
