In the punting data, we find the average distance punted and hang times of 10 punts of an American football as related to various measures of leg strength for 13 volunteers. What is the purpose of this study?
1) To determine the correlation between leg strength and punting distance
2) To compare the hang times of punts with different measures of leg strength
3) To analyze the impact of leg strength on the accuracy of punts
4) To investigate the relationship between leg strength and punt trajectory
