Write 5 descriptive, detailed sentences discussing the results. Discuss the strength and direction of the correlation Are the results expected? What do these results tell you about the relationship of the two variables? If strong correlation, is it due to causation, and underlying cause or coincidence? State the slope of the regression line and a give a sentence to explain what it means. Choose a value of the explanatory variable and use the equation of the regression line to predict the average response variable. h. Show set-ups to calculations. i. Write a descriptive sentence explaining what the prediction tells
