Uncategorized Assignment-helpRequired ResourcesRead/review the following resources for this activity:Textbook: Chapter 9LessonScenario/SummaryThis week you will submit the second part of the course project. You completed Part I in Week 6 and will complete Part II this week.Hypothesis Testing is the use of statistics to determine the probability that a given claim is true.In Part II of this project, you will choose a data set, review claims and perform hypothesis testing and make a decision. You will then complete a write-up that includes the calculations.The government logs the number of documented births, deaths, marriages and divorces; however, it is possible to have undocumented cases. In part II of this project, you are going to test claims about total births, deaths, marriages and divorces.DeliverablesChoose a Data Set.Go to https://www.cdc.gov/nchs/products/nvsr.htm (Links to an external site.)In the search bar type: Births, Marriages, Divorces, and Deathsscreenshot of CDC website toolbarPick a DataSet and download the PDF document and make note of the volume, number, and date. For example you could use the National Vital Statistics Reports,screenshot of National Vital Statistics Reports webpagePick the same month/year combination for each data set. For example, choosing September of 2009.screenshot of example datasetPreliminary CalculationsCreate a summary table for 1. Live Births, 2. Deaths, 3. Marriages, and 4. Divorces highlighting the mean, median, sample standard deviation, minimum and maximum values for each the data sets. You will have FOUR tables using the list of values of each state, the District of Columbia and Puerto Rico (You will have 52 numbers for each data set).Summary Table for _________Mean Median Standard Deviation Minimum MaximumHypothesis TestingWith the information that you gather from the summary tables, test the following (you can use excel when appropriate):Determine if there is sufficient evidence to conclude the average amount of births is over 5000 in the United States and territories at the 0.05 level of significance.Determine if there is sufficient evidence to conclude the average amount of deaths is equal to 6000 in the United States and territories at the 0.10 level of significance.Determine if there is sufficient evidence to conclude the average amount of marriages is greater or equal to 2500 in the United States and territories at the .05 level of significance.Determine if there is sufficient evidence to conclude the average amount of divorces is less than or equal to 4000 in the United States and territories at the 0.10 level of significance.For each of the tests above, in your report, be sure to—Clearly state a null and alternative hypothesisGive the value of the test statisticReport the P-ValueClearly state your conclusion (Reject the Null or Fail to Reject the Null)Explain what your conclusion means in context of the data.Lastly, propose and conduct your own test of hypothesis about the Birth, Death, Marriage and Divorce data that you have been analyzing. Make sure to follow the five steps above.Required SoftwareMicrosoft Office: Word and ExcelUse a personal copy or access the software at https://application.chamberlain.edu (Links to an external site.) .GradingThis activity will be graded based on the Course Project grading rubric.Course Outcomes (CO): 6Due Date: Course Project Part II By 11:59 p.m. MT on Sunday of Week 7RubricWeek 7 Project: Part IIWeek 7 Project: Part IICriteriaRatingsPtsThis criterion is linked to a Learning OutcomePart II: Choose a Data Set & Preliminary Data5.0 ptsProficient.
