Course Project - Phase 5, statistics homework help
This week you will submit Phase 5, the final phase, of your course project. For Phase 5 of your course project, you will want to review your instructor's feedback from your Phase 4 submission and make any necessary corrections. Remember if you have questions about the feedback to ask your instructor for assistance. Once you have made your corrections, you will make your final submission for the course project. Below is a summary of the expectations for Phase 5 of the course project: Introduce your scenario and data set. Provide a brief overview of the scenario you are given above and the data set that you will be analyzing. Classify the variables in your data set. Which variables are quantitative/qualitative? Which variables are discrete/continuous? Describe the level of measurement for each variable included in your data set. Discuss the importance of the Measures of Center and the Measures of Variation. What are the measures of center and why are they important? What are the measures of variation and why are they important? Calculate the measures of center and measures of variation. Interpret your results in context of the selected topic. Mean Median Mode Midrange Range Variance Standard Deviation Discuss the importance of constructing confidence intervals for the population mean. What are confidence intervals? What is a point estimate? What is the best point estimate for the population mean? Explain. Why do we need confidence intervals? Based on your selected topic, evaluate the following: Find the best point estimate of the population mean. Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown. Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations. Write a statement that correctly interprets the confidence interval in context of your selected topic. Based on your selected topic, evaluate the following: Find the best point estimate of the population mean. Construct a 99% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown. Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations. Write a statement that correctly interprets the confidence interval in context of your selected topic. Compare and contrast your findings for the 95% and 99% confidence interval. Did you notice any changes in your interval estimate? Explain. What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain. Discuss the process for hypothesis testing. Discuss the 8 steps of hypothesis testing? When performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why? Perform the hypothesis test. Option 1: Original 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. Based on your selected topic, answer the following: 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? What is the P-value? What is the critical value? What 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. Conclusion Recap your ideas by summarizing the information presented in context of your chosen scenario. Please be sure to show all of your work and use the Equation Editor to format your equations.

Make sure to use a .doc, docx, or rtf file format and attach the file when submitting. Also, these assignments have a minimum of five (5) required sources. While the source report can count as one source, this means you need to find additional sources to add detail and support to your answers. Look for real world examples in the news, peer reviewed journals, etc. For more information about the assignments, refer to the assignment and its grading rubric on Blackboard.Prompt:Below is a chi-square and Cramer’s V statistic from Maricopa County’s Sheriff Offices’ Annual Report (2014-2015). The tables tests the relationship between whether a driver had an item seized by that driver’s race. The chi-square is significant, so a relationship exists. What does this tell us about the Maricopa County Sheriff's Office? How does the Cramer’s V weigh in here? In other words, according to this data, does MCSO discriminate based on race?

Choose two of the following three questions and post your answer:1. In your own words, what is a nonparametric test? What is a parametric test (Section 13-2)?2. In your own words, identify an advantage of using rank correlation instead of linear correlation (Section 13-6).3. In your own words, what is the difference between a nonparametric test and a distribution-free test (Section 13-7)?use your own words!!Replies:Andressa- 1. In your own words, what is a nonparametric test? What is a parametric test (Section 13-2)?The parametric test is the hypothesis test which provides generalisations for making statements about the mean of the parent population. A t-test based on Student’s t-statistic, which is often used in this regard. The t-statistic rests on the underlying assumption that there is the normal distribution of variable and the mean in known or assumed to be known. The population variance is calculated for the sample. It is assumed that the variables of interest, in the population are measured on an interval scale.The nonparametric test is defined as the hypothesis test which is not based on underlying assumptions, i.e. it does not require population’s distribution to be denoted by specific parameters. The test is mainly based on differences in medians. Hence, it is alternately known as the distribution-free test. The test assumes that the variables are measured on a nominal or ordinal level. It is used when the independent variables are non-metric.3. In your own words, what is the difference between a nonparametric test and a distribution-free test (Section 13-7)?Nonparametric Test: Those procedures that test hypotheses that tests hypotheses that are not statements about population parameters are classified as nonparametric.Distribution free procedure: Those procedures that make no assumption about the sampled population are called distribution free procedures.Greg- Rank correlation had an advantage over linear correlation in that it can be used when data is not normal, but it's either categorical or ordinal. Linear correlation only applies when the data is normal and follows a linear pattern. Rank correlation allows us to find the correlation for data that does not fit this. Parametric tests are used when we have assumptions about the distribution of the population that the data was taken from. An example of this would be t tests. In contrast, nonparametric tests are not based on such assumptions and the data can be from a population that is not normally distributed. The Wilcoxon test is a nonparametric test.

Scenario (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 title
The salary (in dollars) for each job
The client needs the preliminary findings by the end of the day. Your boss asks you to first compute some basic statistics and then analyze the results in the four questions given in the Excel spreadsheet.
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.
