STAT 2002 Walden University Week 1 Classify Statistical Scenarios Questions
Consider the following questions:How much does milk cost on the East Coast of the United States? How many minutes does it take to drive 30 miles at an average speed of 55 miles per hour?What is the age difference between you and your siblings?How many hours of sleep do teenagers get during the school year compared to summer vacation?Define each question as being or not being a statistical question and explain why. (75–150 words, or 1–2 paragraphs)Joan Horton is a building contractor whose company builds many homes every year. In planning for each job, Joan needs some idea about the direct labor hours per square foot required to build a home. She has collected sample information on the labor hours for 10 jobs during the past year. (300 words, or 4 paragraphs) Job12345678910Hours245291353118152402351242595173Calculate the mean for this sample. How can Joan use this information?Calculate the median from this sample. If Joan had to select the mean or the median as the estimate of direct labor hours, what factors about each statistic should she consider before making the decision?Calculate the sample variance and standard deviation. How can Joan use these values in planning future jobs?One of Joan’s competitors, J.M. Sawyer, has numbers claiming that his crews average 350 hours per square foot, with a standard deviation of 50. Sawyer further claims that his company is more consistent in direct labor hours applied to houses than Horton’s company. Who is right, and why?The weekly total of hours for the servers and the cooks for a small restaurant are listed below. Find the range, variance, and standard deviation for each set. Which set of data is more variable?

Ashworth College Environmental Pollution Survey & Data Analysis Presentation
Gather and Analyze DataYou have been charged with creating a survey for your community! The community is interested in having you create a survey and present the results at the next town hall meeting. In this project, students will: Learn about quantitative variables.Learn to analyze data for measures of central tendency (mean, median and mode)Learn to create an effective presentation with real-world conclusions. To complete this project you will: Think of a problem within your community or workplace. The problem needs to be something others will have an interest in solving or will want to share reactions to.Create a 10 question survey with quantitative variables (number) on a topic you are interested in. Think of questions where 0 is dislike there is a scale to 4- like. Another way to do this is using 0-never, 1 sometimes, 2 frequently, and 3 always.Administer the survey to a minimum of 10 people.Analyze your data for the mean, median, and mode of each questions.Create a visual from this chapter: bar graph, box and whisker plot, histogram, stem and leaf plot. etc.Compile the information into a slide presentation, of at least 5 slides, to present at the next town hall. The presentation should present: the mean, median, and mode of each question, the visual of the data, and conclusions based on the statistics you found in the survey.

Rasmussen College Salary Distributions Hypothesis Testing Report
CompetencyGiven a real-life application, develop a hypothesis test for a population parameter and its interpretation.InstructionsScenario (Information repeated for deliverable 01, 03, and 04)A major client of your company is interested in the salary distributions of jobs in the state of Minnesota that range from $30,000 to $200,000 per year. As a Business Analyst, your boss asks you to research and analyze the salary distributions. You are given a spreadsheet that contains the following information:A listing of the jobs by titleThe salary (in dollars) for each jobIn prior engagements, you have already explained to your client about the basic statistics and discussed the importance of constructing confidence intervals for the population mean. Your client says that he remembers a little bit about hypothesis testing, but he is a little fuzzy. He asks you to give him the full explanation of all steps in a hypothesis testing and wants your conclusion about a claim that the average salary for all jobs in the state of Minnesota is less than $75,000.Background information on the DataThe data set in the spreadsheet consists of 364 records that you will be analyzing from the Bureau of Labor Statistics. The data set contains a listing of several jobs titles with yearly salaries ranging from approximately $30,000 to $200,000 for the state of Minnesota.What to SubmitYour boss wants you to submit the spreadsheet with the completed calculations. Your research and analysis should be present within the answers provided on the worksheet.
