Slide 3. Construct a Scatterplot Below.

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 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. *Hint: You only need to find y-hat or y-bar (not both).

*Note: Refer to the deliverable instructions for a breakdown of the PowerPoint requirements.
