The accompanying data file shows life expectancies (in years) and obesity rates (in %) for the 50 states and the District of Columbia.

a-1. Find the correlation coefficient between life expectancies and obesity rates. (Round final answer to 3 decimal places. Negative amounts should be indicated by a minus sign.)

a-2. The correlation coefficient implies that life expectancies and obesity rates have a relatively: multiple choice

• strong positive linear relationship.
• strong negative linear relationship.
• weak positive linear relationship.
• weak negative linear relationship.
