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.What do these three proportions tell you about customer satisfaction at A1 hotels? What graphical displays of data would you use to understand or explain the results of the survey?What is the point estimate of the proportion of all recent clients who were “dissatisfied?” Develop the 92% confidence interval for the proportion of all recent clients who were “dissatisfied.” Interpret what the confidence interval tells you about the proportion of all recent clients who were “dissatisfied.” What is the corresponding margin of error? How can the margin of error be decreased?Develop the 92% confidence interval for the proportion of all recent clients who answered “Poor” to room quality. Interpret what the confidence interval tells you about the proportion of all recent clients who answered “Poor” to room quality. What is the corresponding margin of error? How can the margin of error be decreased?Develop the 92% confidence interval for the proportion of all recent clients who answered “Poor” to food quality. Interpret what the confidence interval tells you about the proportion of all recent clients who answered “Poor” to food quality. What is the corresponding margin of error? How can the margin of error be decreased?Develop the 92% confidence interval for the proportion of all recent clients who answered “Poor” to service quality. Interpret what the confidence interval tells you about the proportion of all recent clients who answered “Poor” to service quality. What is the corresponding margin of error? How can the margin of error be decreased?Conduct a hypothesis test, using both the p-Value Approach and 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 level of significance. Do not forget to include the correctly worded hypothesis and show all of the steps required to conduct the hypothesis test.What would be possible effects of a lower and then of a higher level of significance?What other hypothesis tests would you use to better understand hotel customer satisfaction?What advice would you give A1 Hotels based upon your analysis of the data?What is the magnitude of the improvement (if any)?How can this study be improved?Write a report that adheres to the formatting and APA expectations outlined on the Citing & APA Resources page (Links to an external site.) in the CSU-Global Writing Center. As with all written assignments at CSU-Global, you should have in-text citations and a reference 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.

Competency Evaluate hypothesis tests for population parameters from one population.   Instructions 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 Deliverable 4 - Hypothesis Tests.xlsx In 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 hypothesis testing and wants your conclusion about two claims concerning the average salary for all jobs in the state of Minnesota. Background information on the Data The 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 Submit Your boss wants you to submit the spreadsheet with the completed calculations, answers, and analysis.
