The variable of % Obesity is the percent of obese residents per state, and the Life Expectancy variable is the average life expectancy in years per state.
1. Create a scatterplot to see the relationship between the variables % Obese and Life Expectancy. [Hint: you might consider changing the x-axis scale] Copy and paste your graph here. a. What is the independent variable?
b. What is the dependent variable?
c. Does there seem to be a linear association between the two variables?
2. Find the correlation coefficient, r and describe the relationship between % Obese and Life Expectancy. Round your answer to 3 decimals. Is the relationship positive or negative; strong, moderate, or weak?
3. Find the equation of the estimated linear regression line, ŷ. Write the equation below and sketch it on the scatter plot.
