(2 pts) Fifty-one sophomore, 42 junior, and 55 senior students are selected from classes with 516, 428, and 551 students respectively. Identify which type of sampling is used and explain your reasoning. (2 pts) You want to investigate the workplace attitudes concerning new policies that were put into effect. You have funding and support to contact at most 100 people. Choose a design method and discuss the following: Describe the sample design method you will use and why. (2 pts) Specify the population and sample group. Will you include everyone who works for the company, certain departments, full or part-time employees, etc.? (2 pts) Discuss the bias, on the part of both the researcher and participants. (2 pts) A local newspaper wanted to gather information about house sales in the area. It distributed 25,000 electronic surveys to its readers asking questions about house sales in the past 6 months. Of the surveys sent out, 3.2% were returned. The results found that 92% of people did not sell their house in the past 6 months and 85% of people would expect a loss if they sold their house. The writer wants to use these results to conclude that the housing market is declining, and we are headed for a recession. Explain the bias and sampling error in this study. (2 pts) Should the writer conclude that the housing market is declining based upon this data? (2 pts) Why or why not? (2 pts) A homeowner is getting carpet installed. The installer is charging her for 250 square feet. She thinks this is more than the actual space being carpeted. She asks a second installer to measure the space to confirm her doubt.

Pfizer has a new drug, Drug B, that it thinks may be more effective. You have been hired to design the test program. As part of your project briefing, you decide to explain the logic of statistical testing to the people who are going to be working for you. Write the research hypothesis and the null hypothesis. (2 pts) Then construct a table like the one below, displaying the outcomes that would constitute Type I and Type II error. (2 pts) Write a paragraph explaining which error would be more severe, and why. (2 pts) Cough-a-Lot children’s cough syrup is supposed to contain 6 ounces of medicine per bottle. However, since the filling machine is not always precise, there can be variation from bottle to bottle. The amounts in the bottles are normally distributed with σ = 0.3 ounces. A quality assurance inspector measures 10 bottles and finds the following (in ounces): 5.95 6.10 5.98 6.01 6.25 5.85 5.91 6.05 5.88 5.91 Are the results enough evidence to conclude that the bottles are not filled adequately at the labeled amount of 6 ounces per bottle? State the hypothesis you will test. (2 pts) Calculate the test statistic. (2 pts) Find the P-value. (2 pts) What is the conclusion? (2 pts) Calculate a Z score when X = 20, μ = 17, and σ = 3.4. (2 pts) Using a standard normal probabilities table, interpret the results for the Z score in Problem 12. (2 pts) Your babysitter claims that she is underpaid given the current market. Her hourly wage is $12 per hour. You do some research and discover that the average wage in your area is $14 per hour with a standard deviation of 1.9. Calculate the Z score and use the table to find the standard normal probability. Based on your findings, should you give her a raise? Explain your reasoning as to why or why not. (2 pts) Tutor O-Rama claims that their services will raise student SAT math scores at least 50 points. The average score on the math portion of the SAT is μ=350 and σ=35. The 100 students who completed the tutoring program had an average score of 385 points. Is the students’ average score of 385 points significant at the 5% and 1% levels to support Tutor O-Rama’s claim of at least a 50-point increase in the SAT score? (2 pts) Is the Tutor O-Rama students’ average score of 385 points significantly different at the 5% and 1% levels from the average score of 350 points on the math portion of the SAT? What conclusion can you make, based on your results, about the effectiveness of Tutor O-Rama’s tutoring? (2 pts)

About Your Signature AssignmentThis signature assignment is designed to align with specific program student learning outcome(s) in your program. Program Student Learning Outcomes are broad statements that describe what students should know and be able to do upon completion of their degree. The signature assignments may be graded with an automated rubric that allows the University to collect data that can be aggregated across a location or college/school and used for program improvements. Purpose of Assignment The purpose of this assignment is to allow the student an opportunity to apply their understanding of cash flow management, break-even analysis, and short-term and long-term financing in starting and growing a business.

Create the presentation in the following format, with at least one slide to cover each of the following areas: Title PageTable of ContentsExecutive SummaryInformation about the IndustryMarketing PlanCompetitor Analysis3 Year Income Statement (Profit & Loss) ProjectionsInclude your assumptions for why and how you will achieve your sales growth and what significant expenses and investments you expect to incur to achieve your revenue goals.3 Year Proposed Funding Schedule (Sources and uses of the funds received.)Break-Even AnalysisAcademic and Business References Review the following scenarios and assumption, and explain how it impacts your decision to expand:After Year 3, the investors are interested in your company expanding internationally to possibly outsource labor or to reduce manufacturing costs. What countries would you expand to first, and why? What factors would you need to consider in making this decision?What is the corporate tax rate in the countries you are considering expanding your business to, and how will that affect your decision to expand globally? (Use OECD Database or another resource to determine the corporate tax rate).The investors want to see a decision tree detailing the decisions you would make if you received $300K now and $200K at the end of three years instead of $500K up front.The investors would like your team to provide advantages and disadvantages of using debt financing versus selling company stock to raise capital for growth.Briefly explain the venture capital process. Does it make sense for your company to raise funds through venture capital? Format your presentation consistent with APA guidelines.
