Deliverable 6 - Analysis with Correlation and Regression
CompetencyDetermine and interpret the linear correlation coefficient, and use linear regression to find a best fit line for a scatter plot of the data and make predictions.ScenarioAccording to the U.S. Geological Survey (USGS), the probability of a magnitude 6.7 or greater earthquake in the Greater Bay Area is 63%, about 2 out of 3, in the next 30 years. In April 2008, scientists and engineers released a new earthquake forecast for the State of California called the Uniform California Earthquake Rupture Forecast (UCERF).As a junior analyst at the USGS, you are tasked to determine whether there is sufficient evidence to support the claim of a linear correlation between the magnitudes and depths from the earthquakes. Your deliverables will be a PowerPoint presentation you will create summarizing your findings and an excel document to show your work.Concept being StudiedCorrelation and regressionCreating scatterplotsConstructing and interpreting a Hypothesis Test for Correlation using r as the test statisticYou are given a spreadsheet that contains the following information:Magnitude measured on the Richter scaleDepth in kmUsing the spreadsheet, you will answer the problems below in a PowerPoint presentation.What to SubmitThe PowerPoint presentation should answer and explain the following questions based on the spreadsheet provided above.Slide 1: Title slideSlide 2: Introduce your scenario and data set including the variables provided.Slide 3: Construct a scatterplot of the two variables provided in the spreadsheet. Include a description of what you see in the scatterplot.Slide 4: Find the value of the linear correlation coefficient r and the critical value of r using α = 0.05. Include an explanation on how you found those values.Slide 5: Determine whether there is sufficient evidence to support the claim of a linear correlation between the magnitudes and the depths from the earthquakes. Explain.Slide 6: Find the regression equation. Let the predictor (x) variable be the magnitude. Identify the slope and the y-intercept within your regression equation.Slide 7: Is the equation a good model? Explain. What would be the best predicted depth of an earthquake with a magnitude of 2.0? Include the correct units.Slide 8: Conclude by recapping your ideas by summarizing the information presented in context of the scenario.Along with your PowerPoint presentation, you should include your Excel document which shows all calculations.

Quantitative and Analytical Techniques for Managers Statistics Questions
The coursework assignment contains three sections. (I included the actual assigment as the first attachment, the second attachment is just to help you do harvard style citations, and the third attachment is the formulas to help solve the problems) You also will need SPSS for third section :)The first section deals with measures of central tendency and dispersion, the standard normal distribution and z-scores, and Pearson’s correlation coefficient. Section 2 covers Ordinary Least Squares regression. For both sections, you should calculate the solutions step-by-step and show your calculations clearly using structured tables as per the tutorials and lectures. In section 3 you are asked to research a question using multiple regression analysis performed via SPSS and to write up your results and conclusions.Please make sure that you cite ALL the sources you’ve used and include them all in your bibliography using the Harvard style. Please read the guidance on plagiarism and how to avoid it and make sure your assignment does not contain any plagiarism. Direct quotations must be placed in quotation marks and the source (author, year of publication, and page number) included in the text. If you paraphrase from a sentence from another source you must cite the source (author, year of publication and page number) at the end of each sentence that contains the paraphrased text.
