Tutoring on the Normal Distribution
Demonstrate the use of the normal distribution, the standard normal distribution, and the central limit theorem for calculating areas under the normal curve and exploring these concepts in real life applications.ScenarioFrank has only had a brief introduction to statistics when he was in high school 12 years ago, and that did not cover inferential statistics. He is not confident in his ability to answer some of the problems posed in the course.As Frank's tutor, you need to provide Frank with guidance and instruction on a worksheet he has partially filled out. Your job is to help him understand and comprehend the material. You should not simply be providing him with an answer as this will not help when it comes time to take the test. Instead, you will be providing a step-by-step breakdown of the problems including an explanation on why you did each step and using proper terminology.What to SubmitTo complete this assignment, you must first download the word document, and then complete it by including the following items on the worksheet:Incorrect AnswersCorrect any wrong answers. You must also explain the error performed in the problem in your own words.Partially Finished WorkComplete any partially completed work. Make sure to provide step-by-step instructions including explanations.Blank QuestionsShow how to complete any blank questions by providing step-by-step instructions including explanations.Your step-by-step breakdown of the problems, including explanations, should be present within the word document provided.

Quality at A1 Hotels
A1 Hotels operates luxury hotels throughout the world. Recently, motivated by some incidents that appeared in the news, they have been concerned about the quality of service. The company has been giving the following survey to its clients after their stay:How would you rate the quality of your room? Select one. Good(G), Poor(P)How would you rate the quality of your food? Select one. Good(G), Poor(P)How would you rate the quality of your service? Select one. Good (G), Poor(P)Any customer who answered “Poor” to at least one of the three questions up above is considered to be “dissatisfied.” Traditionally, 40% of customers have been dissatisfied.A1 Hotels would like to study customer satisfaction. Therefore, 200 survey responses were recently chosen at random for analysis. The complete data set is in the file named Hotels.Managerial ReportPrepare a report (see below) for A1 Hotels that summarizes your assessment of customer satisfaction. Be sure to include the following seven items in your report.To summarize the data, compute the proportion of all clients thatAnswered “Poor” to room quality.Answered “Poor” to food quality.Answered “Poor” to service quality.Develop the 92% confidence interval for the proportion of all recent clients that were “dissatisfied.” What is the margin of error? What are the lower (or left) and upper (or right) endpoints of the confidence interval? Interpret your results.Develop the 92% confidence interval for the proportion of all recent clients who answered “Poor” to room quality. What is the margin of error?

What are the lower (or left) and upper (or right) endpoints of the confidence interval? Interpret your results.Conduct a hypothesis test (using either the p-Value Approach or the Critical Value Approach) to determine if the proportion of all recent clients is more dissatisfied than the traditional level of dissatisfaction. Use α = 0.08. Do not forget to include the correctly worded hypotheses and show all the steps required to conduct the hypothesis test.What advice would you give to A1 Hotels based upon your analysis of the data? What is the magnitude of the issue? How can this study be improved?Write a report that adheres to the Written Assignment Requirements under the heading “Expectations for CSU-Global Written Assignments” found in the CSU-Global Guide to Writing and APA Requirements. As with all written assignments at CSU-Global, you should have in-text citations and a reference page. An example paper is provided in the MTH410 Guide to Writing with Statistics. (link provided at the bottom of the page)Submit your Excel file in addition to your report.Requirements:Paper must be written in third person.Your paper should be four to five pages in length (counting the title page and references page) and cite and integrate at least one credible outside source. The CSU-Global Library is a great place to find resources.Include a title page, introduction, body, conclusion, and a reference page.The introduction should describe or summarize the topic or problem. It might discuss the importance of the topic or how it affects you or society as a whole, or it might discuss or describe the unique terminology associated with the topic.The body of your paper should answer the questions posed in the problem. Explain how you approached and answered the question or solved the problem, and, for each question, show all steps involved. Be sure this is in paragraph format, not numbered answers like a homework assignment.The conclusion should summarize your thoughts about what you have determined from the data and your analysis, often with a broader personal or societal perspective in mind. Nothing new should be introduced in the conclusion that was not previously discussed in the body paragraphs.Include any tables of data or calculations, calculated values, and/or graphs associated with this problem in the body of your assignment.Document formatting, citations, and style should conform to the CSU-Global Virtual Library CSU-Global Guide to Writing and APA: Introduction. A short summary containing much that you need to know about paper formatting, citations, and references is contained in the New Sample APA Paper. In addition, information in the CSU-Global Virtual Library under the Writing Center/APA Resources tab has many helpful areas (Writing Center, Writing Tips, Template & Examples/Papers & Essays, and others).

Discuss Methods of Validity in Test Construction
In 2002, Boholst constructed a Life Position Scale for the purpose of finishing his dissertation. The construct life position was one of the variables he studied in his doctoral dissertation titled, The Influence of Life Scripts and Life Positions on Psychopathology and Positive Mental Health: A Structural Equation Modeling. He had to construct this scale because there was no available one at the time. In 2005, he and two other authors wrote another article that found modest correlations between Life Positions and Attachment Styles—validating the scale by establishing the relationship between life positions and a variable that was theoretically argued to have conceptual parallels or to be “similar” with it. In 2012, Isgor and two other authors translated the Life Position Scale into Turkish and established its reliability and validity.This is often a realistic scenario where a tool slowly attains credibility by a gradual validation process across the years—often by different authors. For example, in 2004, Weisner wrote his doctoral dissertation in the University of North Texas on the relationship between Affective Traits and Life Positions. Hadzi-Pesic and others more recently (2014) validated the Life Position Scale and found correlations with alcohol addicts’ personality. For this task, write a paper that addresses the following:Discuss the different types of validity that have been employed—whether implicitly or explicitly to validate the life position scale. It is ideal therefore to read articles in chronological order starting with the A Life Position Scale, Life Positions and Attachment: A Canonical Correlation Analysis, and Life Positions Scale Language Equivalence, Reliability and Validity Analysis.Length: 7-10 pages, not including title and reference pagesYour assignment should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards. Upload your document and click the Submit to Dropbox button
