BUSI 230 Liberty University Wk 1 Frequency Distribution Discussion
You will submit a final report, written in Word (or similar word processing software), based on your findings and submissions from parts 1-4. It is highly suggested you not submit this paper without first reviewing all the feedback from your instructor on submissions from weeks 1-6. Be sure to ask any questions you may have on your feedback.This final submission should be three paragraphs and summarize your entire project. It will be submitted through SafeAssign, Liberty’s Plagiarism software on BlackBoard. The project must be submitted in paragraph form and not just a list of the calculations from your project. Be sure your paragraphs flow (not just listing the answers to the questions, but complete sentences with transitions) and are written in third person. You are presenting your results to a nonstatistical audience, do not describe the calculations, describe your results. It should include the following:Paragraph 1:Brief summary of the article, including the sourceLink for article: https://www.usnews.com/higher-education/online-education/articles/2017-04-04/us-news-data-the-average-online-bachelors-studentDefine the population, sample, and statistic for the studyStatement of the two claims in the article that were tested in this projectNull and alternative hypothesis for both tests run for this project (in words)Paragraph 2 (address the claim about the mean):Summary of sample statistics (mean, standard deviation, median, quartiles, sample size)Confidence interval, along with interpretation of the confidence intervalDescription of hypothesis test (alpha, test statistic, p-value, conclusion, interpretation)Paragraph 3 (address the claim about the proportion):Summary of sample statistics (sample size, successes, proportion)Confidence interval, along with interpretation of the confidence intervalDescription of hypothesis test (alpha, test statistic, p-value, conclusion, interpretation)

CompetencyGiven a real-life application, develop a hypothesis test for a population parameter and its interpretation.InstructionsScenario (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 an excel spread sheet. that contains the following information:A listing of the jobs by titleThe salary (in dollars) for each jobIn 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 a hypothesis testing and wants your conclusion about a claim that the average salary for all jobs in the state of Minnesota is less than $75,000.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.What to SubmitYour boss wants you to submit the spreadsheet with the completed calculations.

spreadsheet indicates a missing value; this means that the associated
individual did not answer the question.ContextIn 2015 college students at a large state university completed a
survey about their academic and personal life. Questions ranged from
"How many credits are you registered for this semester?" to "Would you
define yourself as a vegetarian?"The researcher randomly selected 325 students from the university; 312 responded to the survey.PromptThe cell-phone datafile is available in the Data section below.Once again, here is the research question for this lab.Based on a recent study, roughly
80% of college students in the U.S. own a smartphone. Is the proportion
of smartphone owners lower at this university?Respond to each of the following in your initial post.State your hypotheses in symbolic form and in words. (The following
should be clear in your answer: the population of interest and the
meaning of the proportion p in terms of the variable Cell.)StatCrunch uses a normal model to estimate the P-value probability. Verify that normality conditions are met. Use StatCrunch to conduct the hypothesis test. (directions) Copy and paste the results (the StatCrunch output window) into your initial post.Give your P-value and interpret its meaning as a conditional probability.State a conclusion that answers the research question. Use a
significance level of 5%. (Your answer should include the P-value and
reference the population and the variable Cell.)

Linear EquationsGet in LinePart 1:For the Unit 5 Discussion Board, you will create a scenario where a linear equation will be used to find the solution. After setting up your scenario, write out the linear equation for your classmates. Remember linear equations will only have one variable with an exponent of one.Part 2:Solve a classmate’s linear equation. Include the steps showing how you arrived at the answer. Does the answer seem reasonable? Why or why not? Keep in mind that Discussion Boards are meant to be constructive exchanges. Click here to see an example.Part 3:Choose your favorite scenario posted by a classmate. Reply to that classmate telling them why their post is your favorite. Change their equation into an inequality. Choose the inequality (<, >, ≤, ≥) that makes sense for your classmate’s problem. How does this change transform the answer? Click here to see an example.Note: Your responses to your classmates must be substantive and advance the Discussion. Substantive means your reply must 1) include comments specific to that particular post and 2) contain information or insight worthy of sharing with the instructor and class.
