Order Form

I need help with a Statistics question. All explanations and answers will be used to help me learn.

Competency

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.

Scenario

According 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.

Concepts Being Studied
Correlation and regression Creating scatterplots Constructing and interpreting a Hypothesis Test for Correlation using r as the test statistic
You are given a spreadsheet

that contains the following information:
Magnitude measured on the Richter scale Depth in km
Using the spreadsheet, you will answer the problems below in a PowerPoint presentation.

What to Submit

The PowerPoint presentation should answer and explain the following questions based on the spreadsheet provided above.
Slide 1: Title slide Slide 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.

I don’t understand this Management question and need help to study.

Jim asked you to join him to present the team’s leadership discussion to Sam and Gloria. The meeting got a little heated, but nothing went beyond your control. Overall, the meeting went very well. You addressed your concerns, highlighted some key problem areas that were shared by the rest of the team, and connected everything back to how their actions are impacting the success of the project. They now realize that their behaviors and actions are putting the project at risk along with many project risks you and the team have identified.

They were also pretty embarrassed with the type of behaviors they displayed in the meeting as the company leaders. Both Sam and Gloria were very receptive to the ideas that you presented to them. In fact, so receptive that they both said they see a lot of leadership potential in you.

“We are both sorry about the whole ordeal. We will both work together to control our emotions and not let it take over us again,” says Sam.

“Yes I agree. I will approve the project budget, but to ensure everyone is on the same page and that project risks are managed properly, we need to see a simple project communication plan and a risk register. We need to understand your approach better going forward,” says Gloria.

Jim turns to you, handing you a template for both the risk register and the communications plan. “You have done such an excellent job throughout this entire project. Would you be willing to complete these plans?”

“Of course.” you say.

“Because of this incident and the leadership that you have displayed over the past few months, we would like you to take over Jim’s position as the new project manager,” says Sam to you.

Assignment

Back at your desk, you start filling out the risk register template. For your risk register, you will need to define 5 negative risks and 5 positive risks and fill out the rest of the information in the template. For your communications management plan, please find any template or ask your instructor for one. You need to account for all communication types with your stakeholder. Please follow the instructions in the template for both deliverables.Calculus 2 center of mass, separable EDs, linear DDEs
