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.

SOLUTION: descriptive statistics, statistics homework.
Doug and David are researchers who examine youth health. Numerous recent studies have
suggested that youth in the 10-15 year old range are increasingly engaged in many hours of
video game playing, they are not active enough (as defined by at least one hour of exercise
per day), and they are disconnected to their family units. However, in some of their own
previous research Doug and David found that although students play a lot of video games
they remain active and engage in sufficient exercise. In their current study they asked
children to keep a log and then to report for a given week the number of hours of video game
playing and exercise that they engage in and also to report the number of dinners that their
families eat together as a measure of family connection. They also collected gender and age
as demographic data. (data chart attached as Jpeg) 1. What are the measures of central tendency for female participants for playing video
games and exercising? 2. What are the variance and standard deviation for female participants for playing video
games and exercising? 3. What are the measures of central tendency for male participants for playing video games
and exercising? 4. What are the variance and standard deviation for male participants for playing video
games and exercising? 5. Develop a frequency polygon that compares male and female participants for playing
video games and exercising. (This can be done using Excel or hand drawn take a picture
and insert) 6. Summarize the findings comparing female to male habits of playing video games and
exercising.

Calculus Colorado State University Minimize Travel Time Discussion
Exploring applied optimization problems that minimize travel time.Part I: Complete the following steps:Read Example 4.34 in Section 4.7 of Calculus, Volume 1.Consider the following scenario:A lifeguard is at point A of a circular pool with diameter 40 m. He must reach someone who is drowning on the exact opposite side of the pool, at position C. The lifeguard swims with a speed v = 3 m/s from point A to point B, and then runs around the pool from point B to point C at speed w = 9 m/s.Find a function that measures the total amount of time it takes to reach the drowning person as a function of the swim angle, θ expressed in radians.Find at what angle θ, in radians, the lifeguard should swim to reach the drowning person in the least amount of time.What is the domain of the function you created in part (a)?Part II: Based on your work in Part I, discuss the following:How do you know that the function you created in Part I has a maximum and minimum value?Discuss how your answers to Part I would be affected if the diameter of the pool increased.For what running speed would it be faster to swim the entire time? What angle would correspond to this scenario?For what angle, , would it take the longest to reach the drowning person?Suppose the pool was rectangular. Respond to the following:Does it still make sense to parameterize using ? Why or why not?If not, what parameter would you use?If so, how does the parameterization change?Set up, but do not solve, this problem with a rectangular pool.Answer the following questions that reference Example 4.34:How do we know that the function T(x) has a maximum and minimum?What restrictions are there on what the domain of T can be in this scenario?Elaborate, in your own words, on why we must evaluate T(0) and T(6).
