When the ballots are counted, the results are reported. However, for important offices such as president or senator in large states, the networks actively compete to see which will be the first to predict a winner. This is done through exit polls, wherein a random sample of voters who exit the polling booth is asked for whom they voted.

From the data, the sample proportion of voters supporting the candidates is computed. Hypothesis testing is applied to determine whether there is enough evidence to infer the leading candidate will garner enough votes to win. Suppose in the exit poll from the state of Florida during the 2000 year elections, the pollsters recorded only the votes of the two candidates who had any chance of winning: Democrat Al Gore and Republican George W. Bush. In a sample of 765 voters, the number of votes cast for Al Gore was 358 and the number of votes cast for George W.

Bush was 407. The network predicts the candidate as a winner if he wins more than 50% of the votes. The polls close at 8:00 P.M. Based on the sample results, conduct a one-sample hypothesis test to determine if the networks should announce at 8:01 P.M. the Republican candidate George W. Bush will win the state.

Use 0.10 as the significance level (α). Case Study – SpeedX SpeedX, a large courier company, sends invoices to customers requesting payment within 30 days. The bill lists an address, and customers are expected to use their own envelopes to return their payments. Currently, the mean and standard deviation of the amount of time taken to pay bills are 24 days and 6 days, respectively. The chief financial officer (CFO) believes including a stamped self-addressed envelope would decrease the amount of time.

She calculates the improved cash flow from a 2-day decrease in the payment period would pay for the costs of the envelopes and stamps. You have an MBA from the University of Phoenix, and work for SpeedX as a business analyst. One of your job duties is to run analytics and present the results to the senior management for critical decision-making. You see this as an opportunity to utilize some of the skills you gained in the Statistics course. Because of your strong understanding and background in inferential statistics, you decide to take up this important assignment.

You have learned any analysis in inferential statistics starts with sampling. To test the CFO’s belief, you decide to randomly select 220 customers and propose to include a stamped self-addressed envelope with their invoices. The CFO accepts your proposal and allows you to run a pilot study. You then record the numbers of days until payment is received. Using your statistical expertise and skills you gained in the class, conduct a one-sample hypothesis test and determine if you can convince the CFO to conclude that the plan will be profitable.

Use 0.10 and the significance level (α). One-Sample Hypothesis Testing Cases Purpose of Assignment The purpose of this assignment is to develop students' abilities to combine the knowledge of descriptive statistics covered in Weeks 1 and 2 and one-sample hypothesis testing to make managerial decisions. In this assignment, students will learn how statistical analysis is used in predicting an election winner in the first case. In the second case, students will conduct a hypothesis test to decide whether or not a shipping plan will be profitable. Assignment Steps Resources: Microsoft Excel®, Case Study Scenarios, SpeedX Payment Times Write a 400- to 600-word statistical analysis paper based on the Case Study Scenarios and SpeedX Payment Times.

I nclude answers to the following: Case 1: Election Results · Use 0.10 as the significance level (α). · Conduct a one-sample hypothesis test to determine if the networks should announce at 8:01 P.M. the Republican candidate George W. Bush will win the state. Case 2: SpeedX · Use 0.10 and the significance level (α). · Conduct a one-sample hypothesis test and determine if you can convince the CFO to conclude that the plan will be profitable. Use the Excel Spreadsheet to show your work. Format your assignment consistent with APA format with at least one (1) peer-reviewed reference and one reference from the assigned readings.

Please include an Introduction, at least one (1) Level One Heading and Conclusion Heading. Outline for a speech Title of your speech Topic Date of presentation Introduction Capture your audience’s attention with a quote, anecdote, or personal experience Build up to your case or the main reason for your speech Summarize the main idea of your speech. Quickly state your three main points First Main Point Second Main Point Third Main Point First Main Point: Working with outline numbered text in Microsoft Word You can move an outline numbered item to the appropriate numbering level On the Formatting toolbar: To demote the item to a lower numbering level click a list number click Increase Indent. To promote the item to a higher numbering level click a list number click Decrease Indent.

You can use this procedure to help you plan your speech and organize your thoughts. Second Main Point: Creating a Microsoft PowerPoint presentation from a Word outline About creating a PowerPoint presentation from a Word Outline PowerPoint uses the heading styles in your Word document Heading styles are applied when you use numbered outlines Heading styles are already turned on for you in this template. For example, each paragraph formatted with the Heading 1 style becomes the title of a new slide, each Heading 2 becomes the first level of text, and so on. Procedure Open the document you want to use to create a PowerPoint presentation. On the File menu, point to Send To, and then click Microsoft PowerPoint.

This procedure makes it easy for you to create a PowerPoint presentation based on the notes you’ve prepared for your speech in Word. Main Point 3: Creating an outline from an existing document allows you to build on work you’ve already done If you use heading styles to create longer documents, you can see a document's organization in Outline view, and use it to prepare your speech. To learn more about Outline view, see Microsoft Word Help. Conclusion Restate your three main points First Main Point Second Main Point Third Main Point Summarize the ideas you’ve presented Return to your introduction or conclude with a compelling remark
