Slide 8: Conclude by recapping your ideas by summarizing the information presented in context of the scenario.Īlong with your PowerPoint presentation, you should include your Excel document which shows all calculations. What would be the best predicted depth of an earthquake with a magnitude of 2.0? Include the correct units. Slide 7: Is the equation a good model? Explain. Identify the slope and the y-intercept within your regression equation. Let the predictor (x) variable be the magnitude. 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. Include an explanation on how you found those values. Slide 4: Find the value of the linear correlation coefficient r and the critical value of r using ? = 0.05. Include a description of what you see in the scatterplot. Slide 3: Construct a scatterplot of the two variables provided in the spreadsheet. Slide 2: Introduce your scenario and data set including the variables provided. The PowerPoint presentation should answer and explain the following questions based on the spreadsheet provided above. Using the spreadsheet, you will answer the problems below in a PowerPoint presentation. You are given a spreadsheet that contains the following information: Your deliverables will be a PowerPoint presentation you will create summarizing your findings and an excel document to show your work.Ĭonstructing and interpreting a Hypothesis Test for Correlation using r as the test statistic In April 2008, scientists and engineers released a new earthquake forecast for the State of California called the Uniform California Earthquake Rupture Forecast (UCERF).Īs 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. Isang taong henyo, siya ang tinuturing ng karamihan na isa sa pinakamaimpluwensiyang siyentipiko sa kasaysayan ng agham. 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. Si Sir Isaac Newton, PRS 20 Marso 1727 / 4 Enero 1643 31 Marso 1727 ) ay isang Ingles na pisiko, matematiko, astronomo, pilosopo, at alkimiko. Determine 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.Īccording to the U.S.
