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.

Statistic using Excel spread sheet/T1-T84 calculator.
The Excel spread sheet and pdf is for Experience 2 Application only.EXPERIENCE 3 ASSISGNMENT Suppose you are representing the employees at a large corporation during contract negotiations. You have a list of the salaries of all the employees at the corporation (The salaries include the many lower level employees and the few high paid management employees) and you plan to find a measure of center (e.g. mean, median, or mode).a. Which measure or center would you use to represent the employees in an effort to support your claim that the average salary of lower level employees is much lower than the national average (for lower level employees) and thus should be increased?meanmodemedianb. Why is this the better choice?Suppose you wish to invest money safely and are trying to decide between stock options in two companies. The average rates of return are the same for both companies but, one company has a much larger standard deviation of its rates of return. a. Which company should you invest in?The company with the smaller standard deviationThe company with the larger standard deviationb. Why is this the better choice? Describe the shape of the distribution for the following and justify your answer:a. The distance people travel to work on a typical day - The horizontal axis is the distance traveled in a person's daily commute. The vertical axis is frequency (number of people with that distance for their daily commute). Shape of distribution:skewed leftuniformskewed rightsymmetricJustification:b. Number of hours of sleep for each night of the week (weekdays only) - The horizontal axis is the day of the week (Monday to Friday) and the vertical axis is the amount of sleep in hours for that night. Shape of distribution:symmetricuniformskewed leftskewed rightJustification:c. Age of first heart attack - The horizontal axis is age. The vertical axis is frequency (number of people who had their first heart attack at that age). The population is people in the US who have had at least one heart attack. Shape of distribution:uniformsymmetricskewed leftskewed rightJustification:d. Scores on the Graduate Requirement Exam - This is a standardized test for people entering graduate school. The horizontal axis would be the person's total score. The vertical axis would be frequency (number of people with that score). The population would be all GRE test takers for a given year. Shape of distribution:symmetricskewed rightuniformskewed leftJustification:EXPERIENCE 2 APPLICATIONYou must use spreadsheet software (e.g. Excel) for this problem. 1. For each state and Washington DC, the percentage of people without health insurance was determined. Given the data set (The file is located in the main Experience folder) create the following using spreadsheet software. Refer to the model/methodology for the desired format. Make sure to use 5-20 classes with a "nice" class width when creating the distribution tables. Make sure to label axes in both graphs. a. Grouped frequency distribution (table) b. Grouped relative frequency distribution (table) c. frequency histogram (graph) d. relative frequency histogram (graph) Submit the completed spreadsheet as a .xls or .xlsx file. 2. A survey of 50 college students was conducted to determine how much weekly income they earned from employment. Given the data set in Applications folder for this experience complete the following. Refer to the model/methodology for the desired format. a. Find the 5 number summary of the data set. Min= Q1= Median= Q3= Max= b. Create a box-plot for the data set using software (Choices include: The boxplot generator linked in the resources area, spreadsheet software, TI-84 (take a picture of your calculator), other software or websites.) Upload your finished file below. Question 2 Part 6 of 9Choose File No file chosen c. Identify any outliers. List the individual numbers that are outliers for this data set. If there are multiple outliers, separate them by commas. d. Give a possible explanation as to why the individual (or individuals) from part c might have a number (or numbers) that are so high (or so low). e. Interpret yourself as a percentile in the data set. First estimate your weekly income from employment (If you are not employed then use 0). Then find the percentile (see book for the formula) for your income using the sample data. Then interpret the percentile using the definition and writing a complete sentence.
