Math Statistics
This course examines the principles of probability and of descriptive and inferential statistics. Topics include probability concepts, measures of central tendency, normal distributions, and sampling techniques. The application of these principles to simple hypothesis testing methods and to confidence intervals is also covered. The application of these topics in solving problems encountered in personal and professional settings is also discussed.
Business Decision Making Project Part 1
Business Decision Making Project Part 1Due Aug 04, 5:59 PMNot SubmittedPOINTS 5 Projectno new messages Objectives: InstructionsAssignment FilesGrading Purpose of Assignment The purpose of this assignment is to provide students the opportunity to demonstrate mastery of their ability to apply statistical concepts to business situations to inform data-driven decision-making. The project is a 3-week project, with part 1 in Week 3, part 2 in Week 4, and part 3 in Week 5. In Week 3, students identify the organization, problem, research variable, methods for collecting data, and show mastery of validity and reliability as applied to data-collection methods.Resources: Week 3 Videos; Week 3 Readings; Statistic Lab Tutorial help on Excel® and Word functions can be found on the Microsoft® Office website. There are also additional tutorials via the web offering support for Office products. Assignment Steps Identify a business problem or opportunity at a company where you work or with which you are familiar. This will be a business problem you use for the individual assignments in Weeks 3-5. It should be a problem/opportunity for which gathering and analyzing some type of data would help you understand the problem/opportunity better. Identify a research variable within the problem/opportunity that could be measured with some type of data collection.Consider methods for collecting a suitable sample of either qualitative or quantitative data for the variable.Consider how you will know if the data collection method would be valid and reliable. Develop a 1,050-word analysis to describe a company, problem, and variable including the following in your submission:Identify the name and description of the selected company.Describe the problem at that company.Identify one research variable from that problem. Describe the methods you would use for collecting a suitable sample of either qualitative or quantitative data for the variable (Note: do not actually collect any data).Analyze how you will know if the data collection method would generate valid and reliable data (Note: do not actually collect any data).

Assignment 1: Testing for Multiple Regression
Assignment 1: Testing for Multiple RegressionYou had the chance earlier in the week to practice with multiple regression and obtain peer feedback. Now, it is time once again to put all of that good practice to use and answer a social research question with multiple regression. As you begin the Assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure the variables are metric level variables.For this Assignment, you will complete this as Part 1where you will create a research question that can be answered using multiple regression analysis.Part 1To prepare for this Part 1 of your Assignment:Review this week’s Learning Resources and media program related to multiple regression.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.Based on the dataset you chose, construct a research question that can be answered with a multiple regression analysis.Once you perform your multiple regression analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Part 1 Assignment:Write a 2.5 -page(Two and a half) analysis of your multiple regression results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output. RUBRIC/EXPECTATIONS FOR THE ASSIGNMENT:Paper includes a clear description of the chosen variables, their unit of analysis, and their levels of measurement. A clear visual display of the data (if appropriate) is also provided, and a detailed description is given about how these quantitative reasoning and analysis skills will translate into the ability to enact positive social change. Overall, the paper demonstrates an excellent understanding of the chosen variables and their utility.Paper is well organized, uses scholarly tone, follows APA Style, uses original writing and proper paraphrasing, contains very few or no writing and/or spelling errors, and is fully consistent with graduate-level writing style. Paper contains multiple, appropriate and exemplary sources expected/required for the assignment.

Unit 5 IP
ManualIn this assignment, you will complete development of the training manual that you began in Week 4. Training manuals are utilized for training new employees including certified medical administrative assistants (CMAAs) who join the clinic. Refer to the IP assignment in Week 4 as you complete your training manual.In this week you will add the following sections to your Training Manual. Review your Week 4 submission of the first part of the training manual and suggestions made by your instructor for improvement. Make those changes and then add the following new sections to the manual: Office Procedures related to Patient Care Various community and patient resources Advance Directives Medical Record Responsibilities Office procedures and guidelines for various forms of documentation (Release of Information and use of the electronic health record)Financial Procedures Financial procedures related to the policies of the organization Accounting and bookkeeping procedures and processes Financial procedures related to the organization's cash flow Description of 2 or more reimbursement models used in the facility, e.g., fee-for-service.

MAT 543 WEEK 7 DISCUSSION:Decision Analysis
Compare the primary strengths and weaknesses of cost-benefit analysis (CBA), cost-effectiveness analysis (CEA), and cost-utility analysis (CUA). Give your opinion on which method you believe to be the most effective in economic evaluation.Using the umbrella decision-making example on page 198 of the textbook, suppose the probability of rain is 0.6, the ruined clothes cost is $30, and the lost umbrella costs are $2. Come to a decision based upon these assumptions, and determine the break-even probability of rain.**PLEASE CITE ALL SOURCES

Statistics discussion
Admissions offices of colleges and universities are interested in any information that can help them determine which students will be successful at their institution.For example, could students' high school grade point averages (GPA) be useful in predicting their first-year college GPAs? Data on high school GPA and first-year college GPA from a random sample of 32 college students attending a state university.The results of the regression analysis are shown below.Discuss conclusions that can be made using a significance level of 0.05.Discuss factors that may determine the unexplained variation in the first year college GPAs
Statistics
Prompt: A major tire manufacturer claims their heavy-duty truck tires have an average usage life of 71,000 miles. The shipping department of the company you work for has been using these tires for several years and feels they are not getting the mileage promised. The manager pulled 25 maintenance records and found an average tire life of 68,050 miles, with a standard deviation of 11,602 miles. He asks you to conduct a test of hypothesis to determine if the actual life of the tires is less than the manufacturer's claim.Response ParametersUse what you have learned about hypothesis testing to answer the following questions. What type of test should you perform? Which of the three equations for hypothesis testing should you use? Why did you choose that one? You may assume tire life is normally distributed.State your null and alternate hypotheses. Why did you choose those values and mathematical operators?What is the value of your test statistic? (Clearly show how you arrived at this value.)Interpret the test statistic: Choose an appropriate confidence level, then evaluate the test statistic using either the critical value or the p-value approach. Why did you choose the confidence level that you did?Clearly state the outcome of your test of hypothesis.What does your outcome mean in statistical terms?What does your outcome mean in terms of the problem?Strict Deadline no extensions.Use the example format uploaded
