Description

Each week, you will be asked to respond to the prompt or prompts in the discussion forum. Your initial post should be 75-150 words in length, and is due on Sunday. By Tuesday, you should respond to two additional posts from your peers.

For the last several weeks, you have been working with this scenario:

ABC Enterprises is a company in which employees must frequently travel for business meetings with clients inside their city limits. Currently, each employee is allotted 40 dollars each day to cover meals while on the road. They are reimbursed for gas and other expenses in a separate budget, so the 40 dollars is only for meals. Employees have complained that this amount is not enough, especially if they had several meetings per day, and HR wanted to investigate. A survey was given to get recommendations for a new daily meal allotment. Although not all responded, 49% of employess did.

Open the spreadsheet. There is more data now.
Weekly Assignment Spreadsheet February fulljk.xlsx

Answer these questions and explain what you did to solve each one. (include your calculations.)

If one survey response was randomly selected, what is the probability that it was given by someone over 39 years of age?

If two responses were randomly selected, one at a time, without replacement, what is the probability that both were given by a male?

What is the probability that a selection was over 55 dollars, given that it was a response from a female?

Search the internet for an article published in the last 18 months on how businesses use probability. Provide the title, author, and the URL. Provide a four-sentence summary of how probability is used in business. Cite your source in APA format.

Time Series Prediction Project (2-3 pages)

Time Series Prediction Project Two choices Option 1: Use one of the US Census time series linked. here (note that the Census will allow you to check “seasonally adjusted” or “not seasonally adjusted.” You’ll almost certainly want “not seasonally adjusted” since it will help you to show that you can deal with seasonality). Option 2: Find another time series of interest to you on the internet (any time series OK, but be sure to include a link to the data.) Question: Perform a time series analysis. Consider is it horizontal? Does it show a trend? Seasonality?Consider smoothing (moving average or exponential smoothing). Include graphs of both. Do you believe they improve the model? Why or why not? Rubric: 5 points, subjective: was this interesting? (interesting data, interesting conclusion, interesting method) 5: very 4: largely 3: somewhat 2: a little 1: no 0: no data 5 points, graphs: 5 attractive 4 good 3 passable 2 OK 1 cringeworthy 0 no graph 20 points, Time series tools considered (horizontal; seasonality; trend; cycle) For each of the four tools above: 5 - considered and clearly explained 4 - considered if somewhat unclear 3 - considered with no explanation 2 - possibly considered 1 - no mention of that tool 0 - none considered 10 points: Smoothing and moving average 5 - judgment given, graphs support 4 - judgment given but graphs don’t support, or good graphs but no clear judgment 3 - no clear judgment and graphs don’t make the argument clearly on their own 2 - no graphs 1 - no clear judgment and no graphs 0 - smoothing not considered.

Course Project- Phase 3

Phase 1 and 2 attachedThis week you will begin working on Phase 3 of your course project. Using the same data set and variables for your selected topic that you used for phases 1 and 2, add the following information to your analysis:Discuss the process for hypothesis testing.Explain the 8 steps of hypothesis testingWhen performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?Perform the hypothesis test. If you selected Option 1 (Salaries):Claim: The average salary for all jobs in Minnesota is less than $65,000. Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.If you selected Option 2 (Patients at NLEX hospital): Claim: The average age of all patients admitted to the hospital with infectious diseases is less than 65 years of age. Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.Based on your selected topic, perform and document the following steps: Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.Is the test two-tailed, left-tailed, or right-tailed? Explain.Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.What is the value of the test-statistic? Show your calculationWhat is the P-value? Explain how you determined itWhat is the critical value? Explain how you calculated itWhat is your decision? Reject the null or do not reject the null? Explain why you made your decision including the results for your p-value and the critical value.State the final conclusion in non-technical terms.Please show your work for the construction of the test-statistic and explain your process for finding the p-value and critical value. You may use the Equation Editor to format your calculation steps on the Word document or attach an Excel spreadsheet clearly showing each calculation for #B4 and #B5, but your answers still need to appear on the Word document. Also, be sure to number each response in your paper using the same numbers as aboveThis assignment should be formatted using APA guidelines and a minimum of 2 pages in length.
