Exercise 18
Please respond to the following questions in Microsoft Word. See attachment bellow with lecture. 1. Mayland et al. (2014) do not provide the degrees of freedom ( df ) in their study. Use the degrees of freedom formulas provided at the beginning of this exercise to calculate the group df and the error df . 2. What is the F value and p value for spiritual need—patient? What do these results mean? 3. What is the post hoc result for facilities for the hospital with LCP vs. the hospital without LCP (see Table 2 )? Is this result statistically significant? In your opinion, is this an expected finding? 4. What are the assumptions for use of ANOVA? 5. What variable on Table 3 has the result F = 10.6, p < 0.0001? What does the result mean? 6. ANOVA was used for analysis by Mayland et al. (2014) . Would t -tests have also been appropriate? Provide a rationale for your answer. 7. What type of post hoc analysis was performed? Is the post hoc analysis performed more or less conservative than the Scheffé test? 8. State the null hypothesis for care for the three study groups (see Table 2 ). Should the null hypothesis be accepted or rejected? Provide a rationale for your answer. 9. What are the post hoc results for care? Which results are statistically significant? What do the results mean? 10. In your opinion, do the study findings presented in Tables 2 and 3 have implications for end of life care? Provide a rationale for your answer.

Devise a null and alternative hypothesis, then perform a one sample z-test using alpha=0.05 if our class is taller or shorter than the average human in the United States. Graphically display your answer and statistically write up results. In addition, determine the effect size of this relationship and interpret.Notes:The average height of adults in the United States is 67.0±3.8 inches. (Note: this is a population SD)Calculate and interpret the effect size (use Cohen’s d):Cohen's d = (Msample - µpopulation) ⁄ σ)Devise a null and alternative hypothesis, then perform a t-test using alpha =0.05 if the students in our class that are born in warm weather months are taller or shorter than those born in cold weather months.

Week 6 Signature Assignment
About Your Signature AssignmentThis signature assignment is designed to align with specific program student learning outcome(s) in your program. Program Student Learning Outcomes are broad statements that describe what students should know and be able to do upon completion of their degree. The signature assignments might be graded with an automated rubric that allows the University to collect data that can be aggregated across a location or college/school and used for program improvements.Purpose of Assignment The purpose of this assignment is for students to synthesize the concepts learned throughout the course. This assignment will provide students an opportunity to build critical thinking skills, develop businesses and organizations, and solve problems requiring data by compiling all pertinent information into one report. Assignment Steps Resources: Microsoft Excel®, Signature Assignment Databases, Signature Assignment Options, Part 3: Inferential StatisticsScenario: Upon successful completion of the MBA program, say you work in the analytics department for a consulting company. Your assignment is to analyze one of the following databases:ManufacturingHospitalConsumer FoodFinancial Select one of the databases based on the information in the Signature Assignment Options. Provide a 1,600-word detailed, statistical report including the following:Explain the context of the caseProvide a research foundation for the topicPresent graphsExplain outliersPrepare calculationsConduct hypotheses testsDiscuss inferences you have made from the results This assignment is broken down into four parts:Part 1 - Preliminary AnalysisPart 2 - Examination of Descriptive StatisticsPart 3 - Examination of Inferential StatisticsPart 4 - Conclusion/Recommendations Part 1 - Preliminary Analysis (3-4 paragraphs)Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you.State the objective:What are the questions you are trying to address?Describe the population in the study clearly and in sufficient detail:What is the sample?Discuss the types of data and variables:Are the data quantitative or qualitative?What are levels of measurement for the data? Part 2 - Descriptive Statistics (3-4 paragraphs) Examine the given data.Present the descriptive statistics (mean, median, mode, range, standard deviation, variance, CV, and five-number summary).Identify any outliers in the data.Present any graphs or charts you think are appropriate for the data.Note: Ideally, we want to assess the conditions of normality too. However, for the purpose of this exercise, assume data is drawn from normal populations. Part 3 - Inferential Statistics (2-3 paragraphs)Use the Part 3: Inferential Statistics document.Create (formulate) hypothesesRun formal hypothesis testsMake decisions. Your decisions should be stated in non-technical terms.Hint: A final conclusion saying "reject the null hypothesis" by itself without explanation is basically worthless to those who hired you. Similarly, stating the conclusion is false or rejected is not sufficient. Part 4 - Conclusion and Recommendations (1-2 paragraphs)Include the following:What are your conclusions?What do you infer from the statistical analysis?State the interpretations in non-technical terms. What information might lead to a different conclusion?Are there any variables missing?What additional information would be valuable to help draw a more certain conclusion?Format your assignment consistent with APA format. Must include references in APA format

CALCULUS EXAMPLE PROBLEMS
• A lake is stocked with 1000 fish. It is found that N(t), the number of fish after t years, increases so that its rate of increase is governed by the equation: dN/dt = k N (10,000 - N) (called the "Logistic Equation"). Show that the rate of change, dN/dt , is a maximum when the population is 5,000 fish.

onstruct a confidence interval for the population mean μ. 27
Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution. The amounts (in ounces) of juice in eight randomly selected juice bottles are: 15.3 15.3 15.7 15.7 15.3 15.9 15.3 15.9Construct a 98% confidence interval for the mean amount of juice in all such bottles.
